According to my mechanic friend, it doesn't matter as long as it fits. I always try to get the right bulb, but they appear to be identical if you hold them up side-by-side.
A quick google search revealed "Since both lamps are used as combination turn-signal and marker lamps, choose the lamp that suits your needs best. If you do a lot of daytime driving and require a long-lasting signal lamp, install the 1034 lamp. If you do a lot of nighttime driving, and do not need to use your turn signals often, choose the 1157 lamp."* * http://www.trifivechevys.com/showthread.php/2818-1157-vs-1034-bulbs-never-knew-this -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
