    New 2018 Tundra SR5 owner here. Love the truck, but there are no puddle lights or other outside lights that will illuminate the doors.

    I have factory running boards. I am thinking some sort of tape light or such that maybe I can tie into the interior lights? That way they would come on with the fob or when I open the doors.

    Has anyone done this? Not sure if the adhesive style would stay on, or if there are different brightnesses that might be better.

    Thanks in advance!

    I applied some narrow LED light bars on the drip edge under my truck. The light bars came with 3m adhesive backing and I cleaned the drip edge really well with denatured alcohol, heated up the drip edge with a heat gun, and then applied the bars. I placed some clamps on the bars/drip edges for a few minutes to make sure they had good contact.

    I got the light bar strips on Ebay and wired them to the cargo light circuit so they come on when I open a door, unlock with the fob, or turn on the dash switch.

    That is nice.. I was thinking I had to do a long strip on each side.. but that actually makes sense to do two small to light at each door. So where did you connect to the cargo lights? I was thinking of running to the underdash light

    I connected mine to the cargo light circuit in the wire bundle/channel underneath the driver side rear passenger door scuff plate. Some folks have connected to the circuit behind the driver kick panel but I found the rear passenger easier to access. To connect behind the kick panel you have to take up the kick panel and the driver door scuff plate. The cargo light wire on my 2015 was a thin, gray wire but I don't know if there was any color change for the 2018 model. Here is a picture of the wire bundle under the rear passenger scuff plate. The cargo light circuit wire on mine is the far right gray wire. You may have to test some wires to find the right one:

    If you need to test some of the wires to find the right one, I can give you some tips to make it easier.

    Yes. They are a close fit to the cab so I had to put the lights underneath, but I like the way the light comes up through the steps. Its nice to see what I'm about to step in, as well as see if anyone is hanging around (or under) the truck at night.

    So you tied into both the driver and passenger sides? I'm assuming that way you didn't have to run wire from one side of the truck to the other? Or I'm missing something... I'm not the most knowledgeable about wiring science Haha.

    No, I ran all the hot wires for my 4 led lights into 1 hot wire to tap the cargo light circuit so, yes, I had to route wiring from the passenger side to the driver side of the truck. You can run the 2 passenger side hot wires into 1 wire to route over to the driver side, then route the driver side hot wires into 1 wire. Then take those two hot wires that are now on the driver side, and route into 1 hot wire to make your cargo light circuit tap. The negative wires from the LED lights can be grounded to any convenient ground point. I found that the frame mounts for the steps were very convenient. I just made sure that I had good contact by sanding a little paint off around the bolt hole and used ring connectors for my negative wires and ran the bolts through the ring connectors. You can follow some of the factory wiring that runs along the frame and then cross over to the driver side near the gas tank. Make sure you place all your wiring in loom to protect from any abrasion and use wire ties to secure the loom to the factory loom or other secure points. Since the cargo light circuit runs on the driver side of the scuff plate, running over to that side was necessary. I also used wiring connectors and waterproof heat shrink tubing wherever I joined my wires. You will also want to use an inline fuse for your hot wire tap on the cargo light circuit. I think the circuit is a 7.5 amp circuit so that was what I used for my inline fuse. Hope this helps!

    One last thing, I recommend using a PosiTap to connect your hot wire to the cargo light circuit. The sequence would be: PosiTap the cargo light circuit wire, connect one end of the inline fuse, and connect the LED positive wire to other end of the inline fuse.

    And as always, disconnect the negative terminal on the battery before tapping any wires to prevent blown fuse issues....

    So I'm about to pull the trigger on the lights. I think I will just tap into the footwell light, that way the lights will fade on and fade off. I should be able to flip the interior light switch to manually turn them one as well. https://www.ebay.com/itm/Running-Bo...rentrq:f644be381670a9ccac0e8e94fff4c123|iid:1

    I think these look fairly decent. I might mount them up on the frame so I get light thrown onto the running boards and the ground around the truck.
