I've got the dectane LED tail lights on my 2000 cab. I've had them for about 9 or 10 months and they've worked beautifully. Yesterday, I realized that the white reverse light doesn't come on on the drivers side. I'm not very well versed in electrical issues, so I thought I would ask for some advice from any of you as to what the problem might be. Thanks in advance

 

Could be the bulb,maybe a fuse. Take the bulb out and see if there are any burn marks on the inside of the bulb. Also check the socket and make sure it is clean making good contact.

 

Remove the led bulb, using 12 volt power source (I use a small battery charger for motorcycles) put the + /red cable end to the center connection and the - black end to the side connection. with power on it should light up, if good

 

There are no bulbs in these lights.

 

Feel kind of stupid. Should've looked at the lights before even posting. Turns out the Reverse light is a standard automotive bulb, not an LED. $4 later, both reverse lights are working.

 

Live and learn. I have the same lights and had no idea about that.

 

Heh. I was gonna point out that the clear bulb from your original light is the culprit. Congrats on figuring it out.
