OEM is nice, but kinda pricey. If coulda gotten it cheaper, I probably would’ve gone OEM.
Instead, I’ve stuck two 5ft LED strips down the underside of the bed rail, and wired it to my trailer hitch wiring behind the bumper through my taillight cavity. It was an easy install thanks to that constant 12v pin #4 on the trailer harness. Wired up the supplied switch and velcroed it to my bed rug.
Install woulda taken way less time, but the harness fuse had blown, so a trip to the auto parts store was necessary.
After all said and done, $24.00 for the led strips (Amazon), $6 for the fuse (AutoZone) Already had extra hookup wire on hand. About 2 1/2 hours, including trip to store. So, maaaaybe 1 3/4 hr. of total time to install and wire up. Pretty happy with the results. No issues to report.
Good luck.
