I'm cleaning up a old pair of 39 tail lights and need to figure out what bulb they use. If I remember correctly I've always used 1157s but when I looked at my stock of bulbs I found that 1034s fit just like the 1057s. So what is the difference??
1034's are a little dimmer, not much.i was always told that a 1157 bulb was 11 candlepower on the small element, 57 CP on the large( braking), don't know how true that is, can anyone back me on this? JimV
