Car vs motorcycle headlight... does it make a difference?
« on: January 28, 2007, 01:43:21 AM »
Anyone know if there's an actual difference between a 7" motorcycle headlight and a 7" car headlight?  Does it make much of a difference?

Reason I ask, I'm looking at going the tri-bar route with an h4 bulb.  For a tri-bar motorcycle headlight it's around $70-$80 (USD).  Or, I can buy a pair of tri-bar headlights for a car for $38.  Probably cheaper if I surfed around.

I want the look but I'm a cheap bastard and leaning heavily towards picking up a pair of car headlights and using one.

Car headlights are designed to "dip" depending on which light it is and what country they're for.  So US lights dip to the right and the driver's side light will dip more than the passenger-side light.

Bike lights should throw the beam straight out with no dip.

That was one complaint about the original 750, they said it had an "automotive" style light that threw a flat beam, so when you're heeled over in a turn, the beam is lighting up the treetops above you and the road below you without lighting around the bend.  They said it should have more of a circular beam.

Sinc the 750 uses a 7" headlight, refitting a more powerful custom 7" light should be easy.
