LED Turn signals?
 
what do you think about these? i believe LED's are supposed to last 7 yrs guarenteed, blinking, on, off, doesn't matter.. cheaper in the long run.. don't you think?

How dramatic is the difference?

but what "Conventional" (incandescent) light bulb can last for 7 years? these LED's actually should last for 10!! the page also said they consume 95% less power than standard light bulbs..
also brighter too!

True, but only to a point - read on:

As I'm sure many of you have seen, there are Cadillacs with full LED taillight setups (maybe the DeVille's?). The REAL benefit is how quickly LEDs reach full illumination versus incandescent bulbs.

I read this somewhere, and if I can find the test, I will post it. But the results were something like this - an LED illuminates something like 1/3 second faster (not sure of that number, but we'll use it for sake of argument) than a standard bulb. Sounds like nothing, BUT: Let's consider the person BEHIND you. If they have the same braking reaction time once seeing your brake lights, they will hit their brakes about 1/3 second SOONER if you have the LEDs as brake lights. Again, this doesn't sound like a lot, but at 70 MPH, 1/3 second translates to about 14 feet!! That is the difference beteween a panic stop and a rear-end collision.

As turn signals, LEDs are basically useless, although they still do "grab" your attention by the way they blink on/off so precisely. But as brake lights they are a legitimate safety upgrade.

Plus, they look cool!

I've tried the 1157 LEDs for my front turn signal lights. They worked nice but since they use a lot less power than normal indacasent bulbs, it made them blink extremely fast as if a bulb burnt out. I retured them after that.

the GOOD led trun signal bulbs don't blink too fast, but they are $60/pair. i can't remember the web site that sells them right now, maybe i'll post it later.

here it is:

oh, and they are $48. but remember, these bulbs are 100 times better than the apc led bulbs.

correction.... these are it

man i wanna change EVERY light bulb to LED except head lights (you need heat to melt snow and ice off your headlight housing), it would be like 50% power drain. and also LEDs light up to full intensity in no time

OK, not knowing this thread was already here, I just started a new thread describing in excruciating detail how to install LED turn signals and get rid of the annoying double-speed blinking.

firelizard May-18th-2007 06:58 PM

The hyper-blink is not a serious problem. It only happens because LEDs don't draw as much power - your car "thinks" it has a burnt out or missing bulb.

The ones that don't do this probably have a resistor or something to burn-off power so it ends up using the same amount of current.

The other solution is to buy an aftermarket flasher.
