Keep water and debris out of your Lucas headlight shell by installing a new o-ring. This o-ring fits under the Lucas ammeter bezel and seals the outer diameter when you secure the ammeter to the shell. Although this o-ring will seal your ammeter it will also help cure vibration by acting as a "cushion".
O-rings are sold in groups of 5. Fits all Lucas ammeters that measure approx 1 3/4" or 2" (choose size you need) which were fitted to many applications from the 1950's through the 1970's Triumph, BSA, Norton, AJS and Matchless motorcycles.
Use the drop down menu to select which size o-ring you desire based off the size of your ammeter
