I use them only on the bikes I ride. If you are older, the cones on the back of your eyes don't work like they use to for light reflection. I use a 6,000 Kelvin (light wave length or frequency) bulb which turns everything white (reflection) or black (nothing there). The brightness is 3X that of a stockHalogen. The draw is 20 amps upon initial startup than it drops to 2.7 amps or 35 watts. This is ½ the draw of a 70 watt halogen. The top quality bulbs last around 20,000 hours and the stock Halogen (55 watts) last 150 hours and the 65 watt (both are Silverstar bulbs) last 100 hours. This information is easily found on Sylvania’s own web site. If you do a search on this subject you will find much information. If you have a H-4 socket I sell these kits for $239. They are very small and easy to put in. I warrantee them as well as guarantee them. You can call or go to my site for information. I give a customers satisfaction money back guarentee on everything I sell as it is the finest quality but not the cheapest. I do not deal in junk.
I seached for HID and found an old post I did.

SilverStar® Halogens
Go to Line No. 3, P/N H4 ST, Design Watts: 55,Rated Life: 150
Or to the brighter Design on the next line, Watts: 60, Rated Life: 50
My facts used in this is going by the average of SilverStar ® Halogens printed material.
There is nothing wrong with any lighting. The lumens (footcandle) it produces and
light frequency that the light source produces to distinguish contrast is the point. A rider who rides 100 hours at night using his headlight in three years has an option of upgrading or not. The tradeoff between cost/hours used would be the owners choice.
