LED 921 Reverse & Cargo Bulbs

[PaulM]

I use the Samsung 2323 T10 10 watt 921 LED backup lights......VERY BRIGHT! Also have them in my Cargo Lamps.....VERY BRIGHT! I'm very pleased with them. Brighter than stock and cause no issues.

Would you recommend 5k or 6k to match the other oem LED lighting for the VLED's?

 

I would recommend 5K from VLED. We did a Sierra 5000K headlights and 5000K LED fog lamps along with reverse, license plate and cargo and it matches VERY well.

 

The factory LED strips tie in perfectly with the headlights and fogs.

I got these for the backup and center cargo lights

but which bulbs to get for the license plate..???

[250motorsportz]

Yup those are the same ones I got too.

 

For License Plate get these: http://www.vleds.com/5k-white-high-power-led-bulbs-194-168-158-1-pair.html

 

 

 

 

5000K Headlights and LED Fogs

[DLEO]

Yeah I have the 55w 5000k for the fog lights but for some reason the 55w wouldn't work for my headlamp and have to use 35w 5000k until they come out with something to make the 55w work with my automatic lights...

 

I just ordered these for the license plate http://www.vleds.com/5k-white-high-power-led-bulbs-194-168-158-1-pair.html.

 

Thanks! Are they hard to put in? I had a company do my Hids

[250motorsportz]

The license plate ones are SO easy!

 

Reach under your rear bumper and feel behind the light > twist the socket to the left and pull out.

 

Remove bulb > install new bulbs and before putting the socket back into the lamp, make sure they both light up as LED's are reverse polarity.

how many lights are needed for backup and center cargo lamp?

 

how many lights are needed for license plate light?

(2) bulbs for each application.

thx so this look right? (reverse, cargo, license plate, and fog lights)

Can someone please explain this disclaimer?

 

WARNING!
Not for use in continuous on applications like dome lights and map lights that can be left on for long periods of time.

 

This is in reference to the 921s from VLEDS

 

 

So if I leave my cargo light on for an extended period of time, is it going to melt the housing?

 

The exception is when the engine is turned off. The cargo and bed lights are on a 10-15 minute timer. Therefore, this is a non-issue.

I wouldn't worry as I'm sure the LED lights run much cooler than the factory bulbs. I did both the cargo and reverse.. it's worth it.. especially the cargo lights.

This kind of disclaimer is usually a sign that the lights are fairly cheaply designed with insufficient heat sinking to allow for continuous duty operation. What'll happen is that the LED die (and then the LED itself) will overheat, dramatically shortening the life of the unit. It won't damage your vehicle. A LED might generate a fraction of the heat per watt compared to an incandescent bulb, but it does require that heat to be efficiently removed from the diode itself- which generally means metal, and requires complexity and expense.

Thanks for the replies.

That's one theory... but VLEDs actually makes a high quality product. Another reason for the warning might be due to VLEDs attempt to put as many LEDs as possible in such a small package. The 921's small size limits the amount of heat sink per LED, so it's likely VLEDs made those bulbs for people who want more output and are willing to accept the shorter on duration trade off. I'm one of them.
