Wow, very impressed and happy!
I installed these in my 2007 Harley Ultra Classic. Install was easy. They are plug and play. No splicing or anything tricky. The plugs fit perfect.
As far as performance: These bulbs are awesomely bright. Much brighter than stock. When riding in daylight with the passing bulbs on, I can see reflective street signs being illuminated! I never had that effect with the stock bulbs. This equals me being much more visible to other motorists. At night, unbelievable how well I can see now. Night and day difference, no pun intended.
Final note the bulbs seem very high quality. The build and fit and finish all. Look perfect. Seems very well engineered and identical to the Harley brand Daymakers!
5 stars!
