Do people actually pay $900 for a set of after market lights ?

When I got the PIAA 510's for the oilhead, I thought $180 was a high price !!!
My personal favorite is the PIAA 40 round series, too large for most bikes, 6.25 inch ( 160 mm ) reflector.
They look out of place on the crash bars on the R65, but with PIAA superwhite lamps installed, you will never go wanting for extra light.
Though you may be needing a high output alternator after stressing the 27 year old charging system too much!
