i have used this as a lamping spotter for about 2 years, it started life as a scope monted one until the switch got smashed in a closing truck door.
so i stuck a switch and home made handle on it and fitted a new 75 watt lamp and long power lead to it. the marks on the lamp are from tape and will come off ok.
it works 100% and casts a good beam,
