Ok people; please by all means tell me if I'm barking up the wrong tree.......BUT!
I was at Pennwood this weekend and we were able to compare a number of different lighting systems, Bob had new Grote lights, with LED projector technology; John had the same LED's as Cheifair and Mayco, with the four rows of individual LED's and no projector. The one thing I noticed that struck me as odd was on low beam, only the one half of Bob's and John's top mounted lamp LED's were lit. When the high beams came on, the lower half of the top lamp lit up with the bottom lamp fully lit up.
So my question to them both was this.......why not have both headlamps the same, with one half lit up for low beam and the other half for high beam. The answer they gave me was that there was only two wire socket to the bottom headlamps, instead of the three to the top. So my answer was.....why not put a jumper from that third wire to the bottom headlamp????? The answer was......you can't do that......you'll blind people........and the world will end.
Why can't we use a low/high beam headlamp in all four sockets? this inquiring mind wants to know.
