Nice and bright

Running lights won’t work

I installed the passenger side, worked great, installed the drivers side, and some how I have no lights except for blinker high/low and fogs on the front of the truck, I have led bar headlights also which are wired to my parking light, idk I’m confused and need help

Thank you for letting us know about this issue. We're always happy to help. This sounds like an installation issue rather than a product defect. We have an installation video that might help you. If you still need help, email support@sparksmith.com and we can walk you through the installation.

Double shot harness

I had it on my truck for maybe a month and it fell apart and burnt my wiring up

All Amber all the time

Looks great, when drl are supposed to be on it turns on both which is cool. I put amber bulbs in all 4 spots looks great and makes the blinker stand out a lot more than before, don’t have led yet but the resistor is mounted and ready for them. Great kit recommend if you want your truck to stand out more than stock without taking away the clean factory look
