Note that the P3496 is a conventional wire filament bulb, however, not an LED. It is filled with Krypton gas, which produces a brighter light, so it won't have the instant illumination feature of the LED type bulbs as used in some new cars and most big trucks and emergency equipment built in the last few years. The P3496 uses the same amount of current as the 1157 on the brake and turn filament (27 watts each), but almost 3 times the current on the tail light filament, which could cause a heating problem in cars with plastic lenses, especially where the lenses are close to the bulb, because the tail lights are on continuously at night, the brake/turn filaments are only on for a short time. The P3496 tail light filaments produce 8 watts of heat, the original bulbs (1157s) produced only 3 watts each.

Hi all - While poking around allpar.com (a good info source for all the Chrysler engine and parts that may be on your Imperial), I found an article about testing of LED "bulbs" for taillights and brake lights - my '66 could use brighter lights as there are many more dim bulb drivers these days. The expensive LED bulbs did not fare well, but a less expensive replacement was the P3496, which seems to replace many common bulbs on American cars. I also found BMW, Volvo and other car owners recommending its use, which is stated to be 40% brighter than the OEM bulbs.
