2018 Tail lamp LED w/BLIS - repair after led driver failure

The tail light strip led around the assembly went out. It flickered a few times so felt confident it wS the driver that failed and not the leds.

You have to replace the entire assembly for about $760 from Tasca, $1000 from the local dealer. That’s friggin crazy 🤬

In a fit of “what’s the worst I can do”, I took a Fien multi master and split the light open, found the wires, and installed 3 new constant current led drivers (Mean Well HLDD-350HW). One to each strip.

It’ll take a **** of an epoxy job to get it sealed back up but it’s better than dumping an insane amount of money due to a $10 part failure.

Figure someone one day will wonder likeI did if this could be done. Yes it can…not the best…but it worked 🤷🏻‍♂️

Yes great info. You might consider gluing it back together with with something like RTV so you can get it back apart more easily someday…

I considered that but was afraid the lens may pop off if it wasn’t epoxied. I ended up using a good bit of epoxy and then rtv in addition to to seal it properly. I did make the wiring for these lights and the drivers external by bringing them out the back rather than keeping it internal. They are soldered into the wiring with their own plug so that it could be disconnected.

If it goes out again, I’ll likely go ahead with replacing it and consider that this could be done better with more care and attention in the future lol.

Hey sir,

I found your forum and was curious if you had any pictures of you sealing the tailight up. I just found out last night that my lower LED ring has went out and don't want to drop the money that they want for a new oem tailight nor go aftermarket so I was thinking about going this route. How is it still holding up?
I have the same problem. Im going to try this fix. Thank you for posting the driver model number. Although i have no idea what I'm doing I'm going to give it a shot.
