Hate to revive an old thread, but I've tried this twice with T4.2 LEDs and failed. The first time, only one bulb ended up working and it was the wrong color so I purchased the alleged color I wanted from a different vendor, and now these won't even remotely fit into the slots! I really want to go LED because I like how the pure white would go with the other lights, but I may just go with OEM climate control bulbs since because guaranteed fit.
Any advice?
