The flashers didn't work with the new bulbs even though the LED relay was installed. I have yet to install the resistors on them.
I'm wondering if someone can tell me why the AMR1422 bases (tail lights) work just fine without resistors but the AMR1422 are not. I suppose I would have to install the resistors on these others to get a definite answer. I haven't done that yet. Will this make a difference? I'm just curious what it is about the base that makes one type of bulb base work and the other doesn't.
Do a search and read the LED conversion thread where I posted some of my findings.
In short, I had to ditch the LEDs in the rear turn signals because the relays just never worked correctly. I tried every combination of everything. I'm still running them for the brake lamps and reverse lamps.
I'm not familiar with the part numbers for the bases but I can tell you that the brake light bulbs are dual-contact. They have one contact for normal running operations (i.e. headlights turned on) and another brighter mode for when the brakes are engaged. The bulb type 1156 is the single-conductor type, which you use for the turn lamps and the reverse lamp. The brakes are type 1157.
