I put the Azure tribar headlight in several years ago with the Sylvania Silverstar bulb and it made a world of difference. I also tried to add passing lamps, but the matching Azure lights were 4.5" and not 4.75". They would have to be installed with Silicone adhesive and I was not happy about that. There are 2 solutions. First Yamaha makes a tribar clear passing lamp that I purchased and installed. It requires the removal of the switch on the left side passing lamp to clear the fixture. The other is to replace the housings on the passing lamps with those that accommodate a sealed beam fixture as they are 4.5" as compared to the units that house a bulb fixture that are 4.75". It looks pretty good with the Azure Tribar in the headlight and the Yamaha tribar passing lamps, but it would look better if they were all Azure.
