joekd, I'm wondering where you got them and how much they cost? Unless they made some engineering marvel in the type of LEDs they use for those and then jacked up the price quite a bit, I find it hard to believe they are as bright as stock bulbs.

I don't mean to rain on your parade, burst your bubble, or prove you wrong

... just making sure people aren't getting the wrong idea about these retrofit bulbs
They look cool, I like them and use to have them but I realized that in the summertime when the sun is shining, people really couldn't see my brake lights... which is why someone honked at me and pulled up along side me to tell me that. I haven't been able to find the amber colored ones... I would still want to use them in the front like you did since that blinker isn't quite as important. I have bright side marker blinkers anyway so it would still be known that my blinker is on from the front view. If you have pictures, I would like to see the rear to make sure I'm not talking out of my ass

... but I'm sure they can't be as bright as #3157 incondescents.
The type of LEDs used in those are standard 5mm LEDs. They can't dissipate heat very well to achieve enough brightness as a standard brake light or turn signal... not even 15 of them. The brightest LEDs that are available now put out 55 lumens per emitter in red, 36 lumens for amber (which I have for my side markers) They are mounted on an aluminum circuit board which has to be mounted to a heat sink to get that bright (the steel quarter-panel is a good heatsink)... the average brake light puts out about 150 - 200 lumens (estimated because a white reverse light puts out about 300 - 400 lumens. With the red lens, it filters out some of the brightness). The 5mm type LEDs put out less than 1 lumen per emitter... straight on their pretty bright because their beams are focused, but stand at an angle and the brightness falls quite a bit, especially with the pillow lens of the tail light it passes through.
Also, yeah, LEDs turn on faster... All LEDs turn on as fast as the ones on the Cadillac Deville
Anyways, enough of my rambling. I would like to know how much your amber colored ones up front were because I would like to get those to do the same. All I can find are the red ones.
