These PIAA lights say they are designed for bikes….. do our Harleys all take a standard H4 bulb?

If anyone can tell me that this one fits my bike I might order one: http://www.shopatron.com/product/pro...PIA70456/353.0

 

I ordered that PIAA bulb…. Hope it doesn’t fry my wiring. I’ve already had issues with wiring on this brand new bike. LOL I’m interested to see what kind of light it puts out.

 

I have the PIAA H4 Extreme White Bulb and love it... Have any of you guys used the PIAA H4 Super Plasma??? I am looking for the blue tint that all the high end cars have, Also, why are the H4 Extreme white bulbs 60W high beam/55W low beam and the H4 Super Plasma 55W high beam/ 110W low beam?? Seems like the low beam would always be less... Just curious??

 

I had the $40 dollar piaa h4 designed for motorcycles,it lasted 3 months.Replaced it with a $20 silverstar which is just as good and is still working after a year.Some people are using the wrong silverstar h4 which is intended for cars.The correct one for motorcyles is the H4ST, 55/60 watt. Best price I've found so far was on amazon.

 

This one?

What's a "blue light"?

 

 

Consumer Reports tested all the major manufactures of high perf bulbs,jan2004 or 2005.They used a light meter and found the bulbs basically about equal.The bluish tint gives the perception of a brighter light,but it isn't. The best light i've seen is a 65/70 osram wired through a relay using 12 ga. wire (in a 5 3/4 " headlight.
