The Ironman replacement fog lights have been specifically designed for a direct bolt-in for the Ironman Deluxe (new and old-style) Bullbars.
With the addition of a large mudguard style washer, both the chrome and black Ironman replacement fog light is suitable for the Opposite Lock bull bar.
The supplied U-bracket is used with a single bolt and inserted and mounted within the Opposite Lock fog light cup.
Once installed into the fog light cup, the entire unit is reinstalled back into the bull bar.
Mudguard washers from the local hardware stores.
