My reverse lights were not working, once in a while one would come on but it was intermittent. I replaced bulbs and still same. Finally I put 2 and 2 together and looked under the rear of the truck (once I again took notice of the hole in the side of the inner bed wall that looked like a trailer plug) and saw that some dumb dumb had spliced into the wires going to the tail lights on both sides to power this plug in the bed that is no longer there. I removed the splices and the wires had corroded so no power was getting through. Surprised the tails and signals worked at all. 

 Now that the splices are done correctly and shrink wrapped all is good. 

 Since I live in a rural area it is very dark, very little ambient light so I installed some led 3157 bulbs in the reverse light sockets and I can now see behind me for a good 40 feet. Very happy with the outcome of all this and it didn't cost a dime. I had all the electrical stuff I needed to fix the bad splices and the bulbs were donated by a friend.

Great outcome abd cheap as it gets. I put some led's in mine too. Best 15 bucks I spent on lighting.

Just for other to know... I do have LED in stock...

 

 

I don't look forward to redoing parts of the rear wiring..... somebody went at them with (aptly named) vampire clamps to install a 5 pin round socket in the side of the bed.

@Mopar1973Man, I did look at the led lights you have. Are the prices each or a pair? Just curious. I'm thinking of swapping the tail/brake bulbs for led as well.

 The one I used for reverse were free bees. No disrespect.

Per bulb.
