    Thing is, I've got two "wrong sided" lens. One's available.

    Most of my riding is urban, with the very occasional night riding in the country. If I'm on a countryside ride, the destination is usually reached by dusk, or just before.

    As I see it, I want an improved headlight that's easy and cheap that doesn't mess around with the original set up too much.

    I have never been impressed with PIAA stuff that I have installed. Some of it is cheap crap IMO.

    Some wiring harnesses have headlight wires that are too small. That and/or a couple of weak switches are the only thing that is going to reduce your voltage. I don't think straight to the battery is going to make that much difference if your system isn't toasted. I don't understand why you would want a relay to switch relays. Relays fail more than the switches in my experience. I use as few as possible. I have a switch on my lights with no relay because the switch is heavy enough to carry the load no problem. I have had that same switch on two different bikes for 25 years now.

    There are heavy duty switches designed to carry high current; most stock headlight switches are not. That is why they activate a relay and the relay carries the high amperage (I know I am not telling you anything you don't already know). And that is why we use a relay to activate a relay that draws current directly from the battery to the headlight. Whew! Too many relays. Yes, relays can fail, but mine have lasted many years with no problems.

    AFAIK, all Airheads switch high beam-low beam through the handlebar switch. That undertank relay switches the "always-on" headlight on and off when the engine is started.

    Yo Bill, glad you mentionrd this. I am planning on a Baja Designs race light with a H4 Hi/Low bulb and fluted lens conversion from the venders. I didn't even think about the switch being load carrying.
