Backup bulb

[skyviewman]

Is there a source where I can go to get bulb info for our 2004 DSDP. No backup light and when I checked the socket was hanging down, split in half and the bulb was gone. I am looking for all the outside bulbs so that in the future I can have spares and not have to take out the bulb to determine what it is. Checked everywhere I can think of and did searches but could not come up with anything.
thanks

Assuming you have two back-up lamps, the easiest way would be to check the bulb in the other one. Mine are #1156 which are pretty standard.

Thanks, I thought it might be 1156. On my Dutchstar the other side is not very easy to get at and I was afraid I would break off the bulb socket as I did with the other if I tried to get it out.

Actually had mine checked on last servicing because one light was out and the shop informed me that there was 1 wrong type bulb. Just something else to check.

My backup lights are a sealed unit light bulb & lens in one caseing about 4" dia. Had to replace one a month ago. Bought it at Pep Boys auto parts for $5.
