I pulled the diffuser but there is no comparison to the LED lighting. Night and day difference. On a scale 1 to 10, stock was 3, w/o diffuser 4, LED 9. No 10 because I know I can increase lighting by adding LED driving lights or the 7" LED light instead of the stock 5 3/4" my bike has.

 

wow, that LED light is bright.

 

that led is bright
i ride at night about half the time, but could not see myself paying anywhere near that for a head light

also, i ride at night in a group alot and one of the guys has some really bright blue/ white type of light and we are always givin him a bunch of crap about how bright his headlight is in our mirrors

 

I looked on HD's website and apparently though don't make one for the Fat Bob twin headlight. That's too bad because I do a lot of riding in the dark. Especially this time of year. If I just missed it on the website someone please let me know

 

+1 what he said.

 

i have got a few PM... the HID unit that i used was not a high low, it was a constant... does not bother me at all actually, i liked it so much i put it in my sport touring as well ha ha ha
here is a pic of the lamp on with HID

 

I used to ride a Honda with an H-4 90/100 watt; nice and bright; not street legal but I never had an issue with the man. Do standard H-4 bulbs fit Dynas and does anybody have any experience with this possible solution?

 

Here is a great comparrison of two 7" lights from the touring section. I will put the truck lite in my Heritage 7" ebay light for $200. Read this link very good write up.

I did a fairly decent comparison when I tried a switch to PIAA’s bulb…….made sure my camera was white balance locked and shutter speed – f locked……. Tried to get basically the very same position for each set of shots.

I find it frustrating that in the UK my twin headlight Fat Bob only ever has one headlight working, one for dip and one for full beam. What a waste. My 15 year old Honda VFR750 has both headlights working for dip and full beam and is much better for riding at night.
