I think Custom Dynamics has a new set up to retro your turn signals into driving lites and turn signals u replace the lens to clear and their new LED bulbs that blink red when activated ,,, they also have a white LED bulb that will blink white with the clear lens installed....
The problem with using the oem turn signals with any type of retro fit bulb is they are not adjustable. IMO that is pointless as you still can't get the light where YOU want it. The Headwinds spot lights are available in a 2" version without the attached turn signal's. Using their mount allows for up and down as well as side to side adjustment. It appears Headwinds offers 3 different bulbs with 2 different wattages and two different beam angles. If my memory serves me correct the amp draw of the 3 different bulbs were 4.6, 10, and 11 (roughly). The hi wattage bulbs really take some juice to illuminate. Now I imagine that the are few companies making auxiliary spot/ driving lights for the Road Glide, I only looked into Headwinds so far.
IMO opinion these LED headlights are not all that. Without a doubt they are bright and do a good job of illuminating the road in front of you. What they don't do is illuminate the shoulders of the road. When going into a corner the light pattern is very specific and it leaves the ground in a hard lean. I'm looking to add supplemental light to eliminate this. I don't get a warm fuzzy feeling running into a corner at 80 mph and loosing my light.
As for led lights not being very bright during the day, lmao. I have found just the opposite, I can pick a vehicle out of a line of cars with led headlights from a good distance. Now the spots may be a different story as they are not intended to shoot down the road but rather flood the road directly in front of the vehicle.
I saw Rich coming up the road last week from as far as my old eyes could see. Actually I think I heard him coming first! :-D
