The reverse is a 921 bulb, like these:Anyone change out the reverse /backup lights or rear turn signal lamps in the 18's yet?
Was looking at those two since it will be the only ones not LED in the GS at least.
Yeah, that's what I figured. Debating whether to change them or not. Backup lights for sure though.The backup lights should be able to be replaced with LEDs with no problems. You will likely need resistors for the turn signals.
Same here. Gm should have kept the European taillights for the American market. I prefer Amber turn signals in back. Much better for visablity.I would be more interested in changing the signals to amber color. Though that would require importing a European or Australian light assembly.
Couldn't you simply replace the bulbs with yellow LEDs and then have yellowish/orangish turn signals?I would be more interested in changing the signals to amber color. Though that would require importing a European or Australian light assembly.
You could, but you would have amber brakes lights too. US cars have brake/turn bulbs as the same one. Euro cars have the brake lamp integrated into the L-shaped strip.Couldn't you simply replace the bulbs with yellow LEDs and then have yellowish/orangish turn signals?
Sorry, just take off the two plastic panels and you can see the plastic screw ins holding the taillight assembly to the liftgate. Once that's off, you can access the reverse lamps. Make sure you're holding the tail lamp when you unscrew it from the car.
Ahhh okay thank you sir, gonna order some LED reverse lights tomorrow. Will update if I have any issues.
In for more details here. I’ve verified there is a slot for the bulb in the tail lamp. I didn’t see any wiring, though. I’ve also seen a picture of how the headlamp switch differs when you have a rear fog option, but have not been able to surface a part number for it.In other German-made cars I've had, there was often the existence of rear fog lamp wiring although it was not used. In my R32 VW all I had to do for the fronts was add the euro switch and the rears were wired, just had to open the plugged hole and put in a bulb holder.
Anyone have a wiring diagram for the 2018's? I'd be happy to research these things and post the results. Also looking to see if the harness for the LED headlamps are the same as the non-LED so LED units could be retrofitted as used ones come on the market.
Then what's the part # for the headlamp switch with front and rear fog buttons? ;-)The part number is the easy part- the wiring diagram is proving hard to find. Even my usual place to buy official repair info doesn't yet have it for this car. There very well could be the wires all in the existing harness...
I also wish GM wouldn't make the front fogs have to be switched on every time instead of just staying in the selected on/off position after a key cycle. My Camaro does the same thing- I have to switch them on every single time. I'm also trying to find a list of all the bulbs in the car, but can't find any two sources that agree with each other. I've seen four different light bulbs listed just for the headlight low beams... after looking in there, I think they are H7's. Low beams are easy to swap- high beams require taking the entire headlamp out, which means pulling the whole front bumper cover. Ugh...
go to a parts retailer site in any home market and you can even see the diagrams for the part numbers, just like we have in the US market. GM provides that info- like what you'd see at gmpartsdirect.com etc.Then what's the part # for the headlamp switch with front and rear fog buttons? ;-)
Hate to disagree, but it’s not that easy. The model is too new. Everything hits pre-2017 Insignia cars.
