Will that [font=Arial, Helvetica, sans-serif][size=3]Penetrator LED 610 fit on fat bars with full wrap handguards?[/size][/font]
[font=Arial, Helvetica, sans-serif][size=3]How big are the batteries and how long will they last?[/size][/font]

Fat bars are not an issue. We have set up several guys that use the Pro Moto billet handguards. I haven't seen any that it will not work on.On some a small spacer is required due to the recessed cap bolt.
we offer the battery powered kit in 2.5 and 5 hr burn times.
