I'm going to buy one of those PIAA super white bulbs for this years riding season(lots of deer here in SW OH).How much improvement over the stock h4 can I expect?

 

They Sylvania white light replacement bulb is only $25 at Auto Zone. Very bright.

 

Thanks

 

The Sylvania Silverstar H4ST ($19.99) at Auto Zone is an amazing upgrade, plug & play.

I got the PIAA Super White Bulb. WORKS GREAT!!!!!! Well worth the investment. It's a little more expensive since it designed for a motorcycle and the vibration it endures. The element is much thicker.

Be sure NOT to touch the bulb when installing. It has a bluish tint to the beam. But it will LIGHT THE ROAD.

 

+1 for the silverstar! I have used them for years. Just put one on the Harley last week. Most bang for the buck! $20 at Advance.

 

first thing i always do with my vehicles is change to silverstar. Well worth it

 

I had the PIAA Extreme White, but the heat from the bulb discolored the reflector. I replaced the bulb with a silverstar ultra and the reflector with an Adjure unit. Ths bulb is bright and the reflector eliminated the dark area in the light pattern.

 

H4ST gets my vote.
