These pics may help in the decision making process-


Low beam comparison-




High beam comparison-

 

if it has H4 bulb, perhaps this bulb ( or similar highpower/high quality one ) would help ?

Also a known trick from car world is to put separate relays for lights only, and new thicker/better wiring directly from battery, to get all volts to the bulb.
As even a small voltage drop makes a difference.

Don't know what kind of wiring is used in HDs from factory.

With better wiring and dedicated relays, the results should be good. Read this to get more info :

Also worth noting is that relays for lights ( don't know if HDs have relays or not ) save the switches, as only small amount of power goes through the switch when relays are used.

 

so will the 5.75 fit in the stock housing? I have installed a PIAA bulb from custom dynamics and it is nice, but I am still not where I want to be.

 

It should. I already contacted Daniel Stern peeps to see what he suggests. The best solution would of course be to upgrade to a 7" lamp but I'd like to stick with my stock Sportster 5.75 lamp.

 

Thanks everyone for your opinions. I have more than enough info now and I appreciate all your input. I think I'll do a bulb upgrade and save the actual headlight for when I get more of the modifications worked out for the rest of the bikes look.

DK with the save. no wasting $ on sealed $399 lamps that will get you killed when they fail.

If you run incandescent lighting , it will work better with full voltage at the light.
Even a 1 volt drop will cause a 7% less power at 14 volts , we want it all at the light.
These kits fit "inside" the headlight housing.
The side benefit is that the handlebar switches will never have to carry the heavy load anymore , just a trigger circuit for the big circuit.

What bulb costs $399 and fails? I use Sylvania Silverstars which are brighter than stock bulbs but still lacking. i would like to see a comparison of the HD Daymaker vs the DK LED. i ride in the dark every morning. i need maximum illumination.

 

i have a HD high performance bulb and it's fine. i'm ditching it (making it a back-up) for an LED. brightness is part of the reason... it's mostley cosmetic though.

i just all my lights but my headlight to led... my headlight is now noticeably DIRTY YELLOW!!! LEDs are pure white.


dingy yellow headlight. theres actually more light coming off my front led turn signals than the headlight.

your comparison is in here:
https://www.hdforums.com/forum/sport...-led-h4-2.html

the HD High Performance bulb, though not included, is no where near as bright as the PIAA shown.

 

Those relay kits from Easternbeaver look really nice ! As does the other one too.
I am sure they do make a big difference, especially if combined with a brand new high quality H4 bulb.
I do like the "plug and play" idea, and the whole thing goes inside your headlight which is cool.

Anyone tried those yet ? Experiences ?
