Adding the LED Accent Lights to Prime Plus & Premium

Thanks for sharing. I finally finished mine last week, took me about 6 hours. I looks awesome!

 

im too chicken to take the light assembly apart! But ill give this a stab on the weekend once i face my fears! I love how it looks. good job on taking on this task!

 

Thanks OP. Ordered from ebay.

 

Actually, the 5-way female connector already has the 12V +ve and ground (black) available, all you have to do is add a pin (I used 2 staples, straighten it) to the connector and connect your LED +ve connection to that pin, and connect the -ve to the black wire (I solder the wire to the circuit board inside the Light module). This 12V is controlled by the day time running light switch, so that's perfect.

Where is this? I just did this last month and not being able to turn them off is annoying me, was thinking of adding a relay to the DRL light switch but this would be easier.

 

This is the same 5-way harness that connects directly to the LED module

It is the connector (and the only one) from the front LED turn signal module. The male (attached to the module) has has 2 wires from the module. But the female (attached to the car) has 4 wires, one with 12V is controlled by the DRL switch on the steering wheel turn signal rod. see the picture below. I believe the 4th wire might be for the fog light. But can't test it since my Premium model does not have the fog light switch on the dash panel.

Thank you! I know what I'm doing this weekend!

 

question for future repairs...i have a 2018 PREMIUM PRIME.
if someday i get some front end bumper damage, and its time for repair/replacement.
and if the light is damaged (likely due to placement)
would it be a good time to order the light module from the ADVANCE trim ?
my guess is it would be a simple swap, only difference would be harness connector that should just plug right in?
might even be able to do fog light retrofit while everything is apart... i'm sure parts are all on 1 page of the bumper assembly.
but i'm mostly interested if the ADVANCE light would be instantly compatible??
insurance claim for bumper repair would cover most of the costs, just have to pay difference for the upgraded lights...
i havent had a claim for bumper repair in 25 years, but good idea to be prepared if it happens.
i was waiting to fix a fog light on my benz for 15 years!!! accident never happened, just sold the car...
this could benefit any unlucky souls whos bumpers get damaged, they could end up with a sweet upgrade for little extra cost.
i dont know if any custom shops are doing this DIY upgrade yet, but if they would it would not be cheap, 4-6 hours?? i'm sure it would be expensive.

 

after looking up the difference in parts, i see that the fog light is part of the main lamp housing, all one big plastic housing.
so you would need the black trim panel with the cutout for the fog light. thats it.
and thinking about it, since the plus or the premium dont have a fog light switch,
likely easiest fix is to splice the wire for the fog into the DRL powered wire as mentioned above.
then accent lights and fog lights are always on if you have the DRL on.

 

So because my Prime is blue, I swapped in 5 blue interior LEDs:

1) Both vanity mirrors
2) Both front door safety lights
3) Rear trunk

I know it may not make the *most* sense not make these bright white, but I’m a male & rarely have to check on my makeup. Lol. The GF was like “what the heck?” when she inevitably pulled down the sun visor and slid the mirror open and saw the blue light. But she said it’s bright enough.

I just think it adds a nice yet more subtle touch than white, and you can sort of drive with them on, I guess. I mean for a bit. They don’t mess with your outside vision:



I swapped in super bright white LEDs in the both map lights & center dome light so I wanted a little variety.



^^ Ok so this blue one for the trunk *probably* would have made more sense being a super bright white like the rest of the interior lights being it’s a large trunk and the white would allow me to see better, butttttt it’s okay for now.

Every bulb is now an LED including the exterior reverse lights & license plate bulbs - all bulbs except for 1: the glove box light, but I’ll eventually get to it:

 

Awesome write-up. Thank you for taking the time to create such a detailed procedure. This will help me out greatly in the thought process for how I’ll add fog lights to my Prime XLE.
