Backup Light - What Gives?
One backup light on the 70 comes on and one does not. If I connect the pos wire to the bottom of the bulb and the ground to the bulb socket, the bulb lights up. When I put the bulb in the housing the bulb doesn't light. Do I need to purchase another housing? Thanks!

More likely to be a grounding problem, a worn/frayed wire (either power or ground), or a bulb socket problem than the housing. There is nothing in the housing [except the socket] that could cause an electrical issue. Use an ohmmeter to search for a poor/bad electrical connection in the socket and/or wiring.

Get a piece of wire and ground 1 end to the neg battery cable then touch the other end of the wire to the metal part of the bulb as in this picture. If the bulb lights the problem is the ground.
