who makes the brightest replacement bulb/ LED that will fit into a stock headlight

 

100 watt hi beam is the highest i've seen. they come with different wattage low beams. Check amazon for good prices. I use 100/60 and have for years.

 

All the LED's are more light then you'll ever need Freak S
No need to find the brightest

 

i got an H4 LED bulb off ebay for like $20, SUPER bright, fits in the stock housing, also has a little built in fan.

 

An FYI that may be worth mentioning here is that my first LED bulb burned out on me during a drag race and threw the code for a headlight issue. Dealer said he reset the code so that running an LED will not cause issues. So they say?

Purchased led plug n play no code on three seperate occasions.
Paid from $65- 85 for them.
Now that I saw this http://www.banggood.com/H4-32W-3000LM-6500K-COB-HiLo-Beam-LED-Motorcycle-Headlight-DC-9-16V-p-1006317.html

I'll try them instead. Can't go wrong on price.

 

may have to try that too

These things have grown in power-consumption/brightness a few times since their introduction. The brightness is likely subjective because a lot of these are just re-badges Chinese products and the lumen output advertising claims could be unreliable.

But, the power consumption in wattage and light color temperature in degrees Kelvin are better indicators because they are controlled by import standards and federal regulations (not perfect, but at least here is a system as opposed to advertising arbitrary numbers.

Most of these LED headlight bulb replacement produce a 6000K light color. Anything from 5000K to 6000K will be a white light.

The real "tell" for these products is the power consumption. They range from as little as 12w to 40w. I'm sure a 50w version will be out soon if it isn't already.

Generally speaking, the more power consumed, the brighter the light. Of course reflector shapes and LED arrangement will affect the beam pattern, which affects the way you perceive the brightness.

I bought his one http://www.amazon.com/gp/aw/d/B00WVJ...LED+Motorcycle

It uses 40w and is very bright. Very close to the first generation Daymaker I had in my Dyna.

Compared to the 25w LED bulb I had in my Sportster, the output is much brighter. The white color is he same, but the consistency and distance is much more.
