from what I gather the 1157 turn signal bulb has two wattages it runs at, 5 and 21. I guess it runs at 5 watts when just on like normal and then 21 when blinking, right? ok and the 1156 just runs at 21 watts so I guess its always at full brightness...sound right? the question is does it matter if I were to use the 1156 on a 98+ integra to get get the full 21 watts at all time. From what I have seen 1997 was the last year they used the 1156 bulbs, now all are 1157 with dual wattages.
