I highly recommend dumping light that comes with bucket and installing Cibie 7" ECE headlight. It has wide even beam all the way across road for much better visibility than spot-beam DOT headlights. With sharp horizontal cut-off so you don't blind oncoming drivers.
DOT Sylvania sealed-beam headlights
ECE Cibie H4 headlights
