What I have found out so far is that the cheap LED's from China can have horrible light patterns.  If the LED does not mimic the location of the filament in a normal bulb - then the reflector does a very poor job of controlling where the light shines down the road.  The cheap LED's throw a lot of light out the sides of the light - and the high beam often doesn't shine down the road as far as the original bulb did......but they do throw a lot of light out on the berms, mailboxes and nearby cars.

This is my favorite "cheap" bulb at the moment....it does a pretty good job.

This one does an excellent job in the 7" light I have on my Ninja Cafe' bike.  The vertical cut off is not real sharp on the low beam and it does allow some light to bleed upward into oncoming traffic - but I believe it is no worse than the lights in the late model pickup trucks.  It throws out a lot of light - but the long distance light does suffer a little bit.  This light is a bit weird as the light for the low beam only comes out the top of the bulb, so the bottom of the headlight is somewhat dark in appearance.  I have not tried to fit this in the stock headlight....so at this point I don't know if you can squeeze it in a stock housing.  It does have the highest lumen output of any bulb I have tried.

I am using a pair of these in my car.  They have a very good light pattern that doesn't make a lot of bright/dim splotches on the pavement, much more light than stock, and there is no fan or black box needed.  I have not confirmed they will fit in the stock Savage headlight housing.

It looks like I may have found a really good H4 bulb.....and one that is really bright (but not cheap as it was $83.22 with shipping).

This light is listed to be 7,000 lumens - most LED's claim to be between 2,000 - 3,500 lumens.

Most of the LED's draw about 20-25 amps - this one draws 25 amps on low beam.....and 50W on high beam as both sets of emitters are working.

The light appears to be far better built than a lot of them that I have reviewed, and the size of the fan and driver is smaller than some.

I will get it installed and let you know how well it works.  The reviews say that it is bright and has a good vertical cutoff on the low beam.
