I purchased this these 5 foot LED strips for $30. I got one set for the running boards and one for the truck bed. They are bright!
5 foot LED strip
I am not using their wiring harness/switch, I am tapping right into the cargo lights. So not only will they come on with unlocking/door opening, but I can switch them on with the cargo light switch to light up the ground and truck bed.
Install instructions for the OEM kit look more difficult than just tapping the cargo lights too. This kits fuse is a 3 amp, so I'm guessing the draw is low enough to not warrant running a power wire straight from the battery or using a relay, especially since all the other courtesy/cargo/interior lighting in my truck are LED's, the load on the system is already much lower over all than OEM.
I also like that I can mount this LED strip in such a way that it lights up the upper part of the running boards and the ground. You'll notice with the OEM kit that the top of the running board isn't illuminated.
I haven't done the install yet, so I don't have photo's.
