OK, I'm old school which means Fog Lights are yellow not white. White lights are auxiliary Driving Lights. Here's my nightmare.... I upgraded the lights on my FRS to led, I went through and did mods on my BMW resulting in a collection of older bulbs many not compatible with my 2019 Crosstrek w/Eyesight. My question and I'm begging for help here, has anybody modded their fog lights to get a true yellow Fog light? I'm looking for a success story here. I'm getting a bit tired of cross referencing, get leds that either don't look right or whatever. I'm considering Diode Dynamics but would like to hear some experience with the yellow fogs. Any other good recommendations? Thanks!
