Adjure® XL1F3HC - XL1 Series Raised Flames Bullet Lights with Clear Lenses

They call this their "Reverse Set screw" or RSS design. The XL housings will not work with their fork mounts. Harley Dressers: they do have a diamond mount kit available for the flush mount Beacons and XL1 bullet lights. Victory Owners: Your electrical system will only allow the use of 10 watt if you use the halogen bullets so you must tell us when you order. There is no problem using the leds.

RSS Design: The way they hold the bezel to the housing is called their RSS design which stands for Reverse Set Screw. There are 4 threaded holes 90 degrees apart on the housing. According to the way you mount the bullets, you put the set screw in the bottom hole with a drop of blue thread locker (included) and screw it in until it is flush with the housing. You then push the bezel over the o-ring until it is flush with the housing so that the hole in the bezel lines up directly over the set screw. You then turn the set screw counter clockwise (loosen) until it is tight against the bezel. No more lost bezels.
