NIce job!!
I would be amazed if anyone noticed high beam on some bikes - mine has a 35/35 bulb which is just brighter than a candle. I have ordered a 35/35 halogen to see if it makes a difference. It is a Bosch BA20d fitting so couldn't just swap an H4. One for the future.
Do you
need a high beam warning light (legally)? I don't know but I am sure this is a new fangled decision of manufacturers just to add things "because they can"
