Rolex:

Are you running high wattage bulbs? If so, you will burn out the sockets pretty fast, they aren't designed for that much current. Neither are the wires.

There are some aftermarket kits with better sockets and wires, you might want to check them out.

The factory sockets on my 300D aren't in all that good a shape, either -- I had a bad contact on the left headlight that I had to clean up after.
