I actually have two switches: an on/off and a high/low. The 55watt is noticeably brighter than the 35w was. My reflector and lens is def' not a high performance setup but works for now.

Whatever you end up doing, make sure the connections are solid. They will get wet, dusty and be subjected to a lot of vibration. Low cost relays may cut the reliability of the system. Keep it simple so it is sure to function when you need it.
So Bruce, IOW you're saying skip the second relay, and just wire the juice through the switch and don't worry about it for a 35w bulb?
