Thanks. I am pleased with the results and have used one of those black cable spirals ties to wrap the two cables together and it look even neater now. I tried putting the light under the bar but that spot seemed too crowded with brake and gear cables + battery + lights so decided to put the lights on top. I am still exploring different bulb combinations. I am now running 35W + 20W and have tried 20W+10W but will be trying 20W + 20W and 35W + 10W and see which combination I like the most. I can also put a third light on a helmet mount because I have switches for three lights and am currently only using two, or place one of these two on the helmet. There are many options. Actually, I think that is the main advantage of building your own lights. It allows you can try different setups until you find the one that best suits your needs or preferences.

Two quick questions for you:

1) Do you think I should tape the vents on the rear of lamps to prevent water from going in? Should I try riding under the rain and see what happens or what? These light were designed to go on the outside of a car so they are probably fine as they are but those open vents make me slightly nervous.

2) Do you have any suggestion for a helmet mount? I am thinking on attaching the spare Minoura clamp that I bought to a piece of plastic and then Velcro that to the helmet.
