I'm sure others have used these before, but I didn't see any threads, so here's my first take.
This is a generic picture. I bought the red ones, 1157R, not the ones shown here.
I picked these up at Autozone for $20/pr
. I was just going to get replacement incandescents, but saw these and figured I'd give them a try.
They seem like good quality, no exposed PCB material like most of the component LED's form ebay and other places. They installed no differently than incandescents, and I can't tell the difference in brightness between these and the incandescents. I liked the idea of no work LED conversion.
Here's the running lights, incandescent on the left, LED on the right.
And here's the brake light.
For detail on the running vs brake on the LED, here is the bare bulb.
The running light has 1/3 of the LED's lit up, brake light has all of them.
Looking at them, I couldn't tell the difference between them, except that the LED doesn't have an LED on the tip, so there's a little dark spot there. It lights up the reflector just the same as the incandescent.
The package says that it's for off road use only, but I don't think anyone will be able to tell the difference. If anyone else has used these, I'd love to hear any long term results.
