You want reasonable price, easy availability for the components, great lighting, and a sense of self satisfaction when the job is done check this link out:
I originally used the single bolt mount idea and mounted a set of $25 lights but was disappointed in the results. Bought a set of FF50's MONTHS after reading the above post, installed them, and really thought I had something new! Glad I went back to review the original post to find out I had accidentally bought the exact lamps mentioned in the article. The cost for the driving lights is about $60 - $70 including the wiring harness, a switch (I didn't use the switch) and a relay.
Here is what I did differently from the article above.
1.) I used a Dremel tool to cut the relief areas for the bolt clearance on the underside of the mirrors. Ain't got no time for files etc. This is why I bought a Dremel!
2.) I measured for proper bolt length and spacers so that the lights juuuusssst clear the wind deflector wings so they still work fine.
3.) I painted the stainless steel bolt and the spacers black so they match the rest of the trim on the bike.
It is perfectly acceptable to use one of the circuits for the headlight to TRIGGER THE RELAY used to energize the lights. Run a wire back to the battery for the +12V and one to the battery for the ground (earth). Fuse the +12V wire and run the +12V and Ground wires to the relay following the instructions that came with the light and follow the rest of the instructions to finish the job. I use the HIGH BEAM circuit as the trigger for the driving lights. The current draw on the high beam circuit is on the order of a few 10's of milliamps so no worries about too much current draw.
I used the high beam as the trigger because I feel that adding discrete switches "uglifies the beauty" of the LT (unless an autoswitch is used) and because I have the drivers pointing WAAAYY down the road which would cause sterility in oncoming drivers if left on. I don't want to reach for another switch.
Lights on high beam = driving lights on. High beams off = driving lights off.
High beams are on when riding in the daylight.
I also mounted a set of yellow reflectored fog lights under the tip over wings. Again, using a very simple home made mount that can't be seen unless the wing is off the bike. They use the low beam lights as the trigger source so they are on as long as the headlight is on. These lights have a very flat beam and are adjusted so that they are very visible to oncoming traffic but do not blind the drivers. Again use the relay that came with the kit, no external switch.
Mods to come: I will eventually change the quartz lamps out for DDM Tuning HID lamps.They run cooler and draw less current than quartz and the color will match the low beam color.
This is the first MC I have owned where the bike can support hanging on a few extra lights and I have been having a party.
Here are the links for some of the other lights I have installed:
Wings of gold This is a great mod for about $20. I never thanked Hans for this post. Thank you Hans, I have really enjoyed my Wings of Amber.
Under side case turn signal led strips
I did this one too. Very impressive amount of light after dark. Will wire up to the driving lights too so they are on all the time.
I have become somewhat(?) of a light whore of late. Next projects will be turn signal led's on the mirrors and installing led strips on the side case trim. You can now buy led's in strips with a protective cover that is black between the led's.
So many lights and so little time. Sigh.......
