IML: Better Bulbs?



Dick -

Thanks for the detailed explanation and potential warning. I think the taillight bulbs have good spacing from the lense on my '66, but will check this before any install.

Using these new bulbs on my other old car ('69 Alfa, if they fit) may be more important, as two drivers behind me have told they didn't see my brake lights. But they always check out OK, so something is "too dim".

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.
