? L E D taillights

the last time I was rear ended, it was due to total negligence of the other driver. that excuse of a brake light coming on quicker, sounds to me more like a reason to convince the wife that, "yes dear, it makes sense to spend $14.99 for a perfectly good bulb whereas the current 99 cent one is perfectly adequate.
the requirement for an eye level brake light is more meaningful than a millisecond faster reaction.

For brake lights in particular, there is one huge advantage going to LED.

Incandescent bulbs light up approximately 0.5 sec after power is applied.
LED light up approximately 0.05 sec after power is applied.

That means the driver behind you gets an extra 0.45 sec to react. May not sound like a lot but even if they still hit you, it will be at a slower speed and therefore should be less serious.

True it's a bit off topic, but you can break it down even further.

At 60mph your car is traveling 88 feet per second. 5260/60=88

At 88 feet per second you are traveling 8.8 feet every tenth of a second. 88/10=8.8ft

Now take the numbers from valhalla360. Even rounding the .45 down to .40 you will travel 35.2 feet in 4 tents of a second. 8.8*.4=35.2 That's more than the length of a standard traffic intersection. So the LED coming on .40 seconds faster than the incandescent will give you an additional 35.2 feet of stopping distance.

A Sure Power flasher cost me extra. Not only will it keep flashing into infinite resistance it will aurvive a dead short and even reversed polarity.

There is no reason to screw around with resistors

Plug and play except with newer nightmare H.A.L. controlled vehicles.

As I stated earlier:

"They have specific flashers or you can add in a resister, or they may come with resisters built-in."

Guess I didn't spell it out clearly enough: Specific flashers that will work with LED's.

The turn signals bulbs are usually the only problem since they flash really quickly with a normal flasher. They have specific flashers or you can add in a resister, or they may come with resisters built-in.

Adding the resistor completely defeats the primary reason for switching to LED taillights, reduction in power.

Hey, I didn't make up the laws of physics. That's just the way it works, really doesn't matter that you don't like it.

I have seen a number of times that the bulbs should be replaced with red LED bulbs because they show up better.

the original bulbs should be adequate, but if you want to throw money away, have at it. I think I have replaced a dozen at most old style bulbs over the years.

22 yo vehicle. I have replaced ONE bulb.

If you have regular tail, stop, turm taillights, can they be changed over to plug & play lights

Not on all vehicles !

Some very new vehicles will "sense" that there is a very low "load" and then report that you have a burned out light bulb !

I somebody is that anal about their tail light brightness, I would suggest getting a set of magnetic lights and put them on the trunk of their car and plug into the 4 flat connector.

They are the same price. Why would you be opposed to purchasing the proper bulb for the location and fixture?
