Any before/after pictures?

 

All I've got is this atm:

 

44W!! My front door floodlight that lights up across the dark street for a 150 foot section of road doesn't use that much.

Compare that to the old 55W sealed halogens that weren't as efficient but more than bright enough.

 

Almost any LED is an upgrade over the stock incandescents.

 

Yeah, but for the price this is just far better.

btw I have no idea if the W numbers are correct.

 

@Octal450 they aren't. There's tons of youtube videos out there on how much companies lie about output on Amazon. Best way is practical experience, which you have.

 

Yeah, I've seen those vids. Especially bogus based on how LEDs are so much more efficient. I've probably got an ampmeter back home, could check the wattage for sh*ts and giggles.

 

Do the older Crosstreks use a 7440 bulb. I looked today and my ‘24 uses a W16W bulb but the Auxbeam W16W shows a small wiring harness off the back of the bulb. The factory harness has the socket for the bulb and attaches to the lens. Don’t know what light to order.

 

My 18 trek is 7443 per DD

 

24 trek is Amazon.com yes W16W.

Same thing. The pigtail is due to the heatsink needed for this bright bulb. Just plug it into the factory harness and tuck it away in the panel.

It should fit just like it did on previous models but I haven't tried that myself. I have an '18.

That's what I was thinking. Thanks for the confirmation.

 

You're welcome!

 

6000lm is crazy bright! Stock backup lights are around 250lm. The brightest Diode Dynamics ones are 700lm. Are these even street legal as in will I pass a state inspection?

 

I am still learning in this space myself so don't take as gospel but...AFAIK things like fogs and backup lights are NOT regulated.

 

What's regulated, and how, would depend on the state, province, or country.

For example, in my state, the idea of "car inspections" might lose a politician their office in the next election.

hmm..see below...am I missing something?? We all know enforcement and inspections are another matter...but.

The National Highway Traffic Safety Administration (NHTSA), a part of the United States Department of Transportation (DOT), regulates automobile headlights in the United States:
Federal Motor Vehicle Safety Standard (FMVSS) 108: This standard regulates all automotive lighting, signaling, and reflective devices, including headlights.
Headlight brightness: Headlights must have a luminous intensity between 500 and 3,000 candelas.
Headlight certification: The DOT and SAE certify headlights that are legal in the United States.
LED headlights: The NHTSA requires that any LED headlight lamp designed and sold by a third party be approved by the NHTSA.

 

There are federal regulations that mandate the existence and sometimes colors of several types of car exterior lights -- turn signals, brake lights, and so on. But headlights are the only ones where the feds require the certification of specific lighting systems, so my guess is that in most jurisdictions those reverse lights are legal.

That said, if the OP leaves for work early in the morning I hope he's provided free sunglasses to all his neighbors.

 

AI still has a ways to go, for sure. I've played with several of the products, and once in a while they're able to totally nail my queries ... but just as often, the results are laughable.

From the standpoint of this forum, it's appreciated if any posts generated by AI are labeled as such. AI content is also used by spammers a lot, and if a post from a new user sounds like AI, I always scrutinize it more closely.

 

Yep. I a computer scientist myself. Started coding in the 70's. What a long strange trip it's been. I redid my query and got the same response without AI.

 

I can't speak for inspection. My state doesn't do them and my previous state only did emissions.

 

15 states have no vehicle inspection:

https://en.wikipedia.org/wiki/Vehicle_inspection_in_the_United_States?wprov=sfla1

 

Oddly (or not), the "old standard" brands seem to be less forthcoming with any claim about lumen ratings or similar.

For example, the Sylvania LED 912 bulbs, which would fit the reverse light sockets but don't have the brightness / output rating anywhere I could find on a quick search.

 

Btw note that emissions testing won't check this. Even I passed in CT with my heavily tuned motor. Cause I didn't touch emissions stuff.

 

We get annual emissions and safety checks. Front suspension and steering, wipers, lamps and headlights aim. I doubt rear bulb brightness would cause an issue.

 

I saw what they do here in MA. They check all bulbs to make sure they work. And they check headlight aim.

 

I personally have tried only a few aftermarket LED bulbs for various vehicles in the last two years or so. LED technology since covid has advanced ALOT IMO!!
While pricing may be a factor for some, I have noticed that quality in some of the more pricier LEDs IS worth the expense as they tend to last much longer. I have yet to try Diode Dynamics newer LEDs, but I can attest to their quality amongst their other fog/spot/driving/ditch lights It is worth the extra coin to cry once I do not doubt their other LEDs would be any different.

Today's LED designs are very close in dimensions to regular filament bulbs or halogens. Gone are the days of only a couple years ago with extended housings with cooling fans, extra diodes, etc.

But...brighter does not necessarily mean better? As with anything, there is a balance between brightness and longevity IMO. Sure you may have a nice bright set of LEDs in the CT, but if you need to change them out too often, is it worth it? Again, just my two cents.

 

Hell, I bought a pair of cheap Sylvania 912 LEDs from an auto parts store, and those were an upgrade over the incandescents... and will probably outlive some countries.

 

I have tested a LOT of LED back-up bulbs on my car including Diode Dynamics, LASFIT, SuperBrightLEDs, Alla, etc... and these are simply the BEST ones ever made.

These are so far above any other bulb I tested. No other design of 7440 bulb came close. It's like having a set of headlights on the back of your car for backing up - and since I often park in dimly light areas, this is absolutely awesome and gives me confidence when backing up, it also works fantastic for lighting things up on the reverse camera.

Reliability wise, I've had these for a year now and no issues. I waited to post this to ensure they wouldn't die.

They have the LEDs on a thin strip back-to-back chips positioned vertically like headlight replacements, matching filament location. You can see the chips in the reflector beads showing that. The rubber grommet is a little tricky to insert, and you have to make sure you rotate them so the chips are firing out at the 9 and 3 position.

One of the Alla bulbs was similar brightness, but had extremely poor build and design quality and I cannot recommend that bulb and would possibly classify it as dangerous, as many other cheap bulbs are.

No, this isn't a sponsored post. I bought these products with my own money.

I bought the 921's for my 24 limited and the bulb will fit the hole and will plug into the harness, but the bulb housing sticks out too far and the cover on the inside of the hatch will not fit over it.

 

Damn. Sorry

It fits all previous years. I'll update OP.

I've had mine now for about 4 years on my 2019 base Trek... OEM back up lights were miserable especially with light tint on the side windows. Old school I do use the camera but I also use the side mirrors since we have those obnoxious concrete strips for driveway.

 

The auxbeam lights can be extremely bright. Bought a pair for the fog lights on my '23 (yellow). Lit up the road like high beams. Got flashed during the day. These were like the 6x brighter. I bought the same thing only different that were like 3X brighter. More within the range of normal.

 

You likely bought the wrong bulbs. If they are not two-sided they will glare. You have to get a bulb designed for that usecase, with two thin sides in a vertical position or else that will happen.

 

I saw that Auxbeam has two different backup LED options. The lower end ones looks similar to the ones I got from Diode Dynamics. The higher end one is huge and I have to wonder if it will burn a hole in the reflector or not even fit.

 

Huh? It won't "burn a hole" lol. They don't get as hot as halogens even. Also they fit fine in pre 2024's.

 

I do think that lights on a car can be too bright... impairing the vision of oncoming drivers and not giving the driver of the car they're on any ability to adjust to night vision.

 

On the subject of reverse LED's, how will they impact oncoming drivers or inhibit the driver's ability to adjust to night vision in the car they are on?

For what it's worth, I put these in my 2023 Crosstrek (the Kimlatar 4000Lumens). They were super easy to install and I've had zero issues w/them. They are such a HUGE improvement to the stock bulbs. The weather is pretty crappy here in the PNW and being able to see when I'm backing up is a game changer.
