I tried running 55 watt passing lamps. Ended up melting the housing.
80/100? Damn, you can cook a steak on that.
I'm using this Crylon headlight below, It's a couple years old and they've got a new model out now. Haven't tried the update.
Second pick is the LED spotlights I'm using.
Best set up I've had in 13 years.
Day or night, straight or twisties, I'm happy.
