Triumph Bonneville T100/T120 Tail Lamp kit.

Updated: May 16, 2023

Don't believe a word of it!  Size does Matter!! How can you live with such a Monstrosity!!! A fender can look good. So I have made a bolt on, plug and play kit exclusively, for those that want a sporty looking Bonnie. Replacing the generous portion of OEM lights brings balance.

Mounted and secured by the same 3 screws that secure stock light. Tail light housing deceivingly floats above fender so no metal-paint contact is made.

Kit is available with choice of 4 different tail lamps. With or without turn signals. Custom aluminum housing finished in Polished or brushed satin, matte black or black gloss with all stainless hardware.  These hand made custom kits are a great deal considering the design and work involved in their being.
