In my case it was something like . Take off lens remove bulb install LEDS. Drive down road come home reverse previous instructions, ship back to supplier. Couple months later open box and repeat previous actions.......including shipping back to supplier. Still waiting on that set to be replaced. They were a Christmas present and here it is August and I still don't have em. So far the set in my other truck is holding up aside from the cargo light. The cargo light will come on and then it starts flashing real fast. The supplier said to take it out and ship it back but it was a bugger to put in. On the other hand it wasn't cheap and it oughtta work!
