I did a search on the forum and google and didnt seem to find many hits.

Has anyone changed out their 3rd brake light bulbs and bed lights to LED bulbs? If so what kind did you go with? I was thinking of changing the 3rd brake lights, bed lights, and reverse lights to LED.

 

I believe the 3rd brake light is a 921.
Which seems to be the same as:
904
904NA
906
906NA
912
916
916NA
917
920
922
158
160
161
161B
168
168A
168NA

192
193
194
194B
194G

194R
2821
2825
2827
2886X
3652
558
579

194 is the most common listing that is sold.

Thanks for the reply! I understand the bulb size, I was wondering if anyone has actually bought LED replacements for the 3rd brake light however.

 

I just replaced the whole thing for an LED version, instead of replacing the bulbs only.

 

I replaced my cargo lights and 3rd brake lights with 4 each x 24 5050smd LED boards. They are very bright.
They come with the plug and play socket harness.
I glued them into the fixture.
Looks and works great for a few years now. Much better lumen output than any aftermarket LED housing. Each board = 350 lumen

I have also changed my reverse and brake lights with Putco LEDs, will need to change to an electronic flasher to avoid hyper-flash.

 

That looks fantastic and exactly what I am looking for, thanks! What did you use for your bed lighting? Did you wire it into the cargo lights?

 

Thanks, it was night and day difference upgrading the factory cargo lights. I got the bed lights from LEDglow . com . They were about $50. I ran the wire thru the front of the bed to beneath the cab, thru a small drilled hole, and up to the cargo light from inside the truck. It makes a hell of a difference.

I just wish the bed lights were more white than blue but they work great.

I got my electronic flasher from superbrightleds . com
the one from autozone was returned, it had a very annoying un-natural blinker click to it, and would delay a moment before beginning to blink, terrible.

My rear brake and reverse lights are Putco 18smd LED, can get you more info if you like.

Here's a walk around vid I took a long time ago of the cargo lights after the install.

3rd Brake Light/Cargo Light/Reverse Light

I have a 2000 Dodge Ram 1500 extended Cab ST truck.

This truck came factor with the 3rd Brake/Cargo/rev light fixture. I replaced it with a LED one. I plugged this in place to the OEM one, blew out my interior, radio, door locks and who knows what else. Thanks for the advice on here, I was able to fix the interior, radio, door locks etc. Issue is, I have no power for cargo light I do have one wire that has power all the time. The brake light works great. Any suggestions where to look to find where I lost power for this cargo light on rear top of cab outside above bed. I've checked both boxes for blown fuses. I did not put the two fuses in the yellow holders because they say air bags. The fuse under the black holder was the one that was blown for the interior cab lights.

I even reinstalled the OEM 3rd brake yada, yada, yada, It too does not work. I knew it would not but I thought what the heck, lets just see.

Do any of you folks have any suggestions what could be wrong and where I should look?

I looked in the service manual provided to me via a link by heyYou but I have a Traumatic Brain Injury and could not find the correct wiring diagram. I found where they showed u how to pull the two screw out that hold the light into the cab and how to un-plug the harness, really, do they really think they needed to tell anyone this let a lone show you a photo of the light? OK, I'm done complaining. Just frustrated. Anyone please help
