Review on Philips 4157NA Long-lasting Miniature Bulb, Pack of 2 by Dushawn Walker

I installed a bulb (amber) in a 2005 4Runner passenger turn signal and it blew out after just a few months. When I took out the burned out bulb to replace it, I was surprised that the amber color had almost completely disappeared from the bulb in such a short time. Seems to confirm what others have commented about the bulb overheating. On the one hand, using the light bulb that the car is designed for is a simple replacement, but the service life is only 3 months? Oh well. The LED versions are always looking better and I've had the good fortune to convert a few bulbs to LED. The trick with LED turn signals in a car that wasn't originally designed for them is that they will hyperflash (e.g. when the bulb is dead) unless you add a load resistor or replace a new relay, designed for your car. I think the next time the bulb goes out (I don't have high hopes for that) I'll take the plunge and spend a little more money on LED bulbs with a new relay (just their load resistance).
