CREE Led Reverse Bulbs
CREE Led Reverse Bulbs
I'm having a problem with these bulbs, when I put them both in, they only stay on for about 10 seconds. But one will stay on if I leave 1 stock bulb in.
Any ideas, like a bigger fuse, or maybe a resistor?

But its weird how if I leave one stock bulb in, and one LED bulb in, they stay on.
But if I put both LED's in they only stay on for like 10 seconds. I didnt think it would be a resistor, seeing as LED's are supposed to use less power, but im at a loss, and cant figure this out.

Yeah, it's a resistor issue. Adding one to the harness will clear up your issue.
The problem is because with both led bulbs installed, the vehicle doesn't see a normal current draw from the bulbs because they require so little energy to operate, so it automatically stops sending what it thinks is "wasted" power to a lighting system that it believes is inoperative.
When you have one stock bulb installed, it recognizes the draw that it would normally receive from one operating bulb and one burnt bulbs, so it continues to illuminate the system because it believes that it is, at least partially, operative.

glad you figured it out.

Or just one on one side
I just used one of these:
Hook one wire up to the 12v positive and the other to the ground. It adds 25w of load to the reverse light circuit. Don't go too big or you could cook wiring or pop fuses.
For reference, stock bulbs are 21w each.

I had/have the same issue currently with my 16 watt CREE LEDs. Checking my options with the tuners to see weather I can just have the current value altered to accommodate lower power bulbs. Saves power and don't have to wire in resistors ><
I find that having one of each (LED and Incandescent) works for the time being.
I took a photo to illustrate the difference in light output and pattern from the two bulbs.
Guess which one was the CREE chip? =P
