Hopefully you're not still using the stock headlight. It's been my experience that good or great light can't really be had without spending some bucks. With my last headlight upgrade on my 02, I shopped around and settled on a quartz "trillient", which cost about $300 and worth every penny. On my later Indian I spent $400 replacing the stock headlight with a "LED Projector" type light and again, worth every penny even if the price DID hurt. I've smacked deer 4 times in my 40 year career with bikes and I'll spend almost ANY kind of money not to do it again! What ever you do, make sure you buy a modern LED light or lights. The difference is amazing and gives you some peace of mind!
