Grover -
I'll see if I can answer all of the questions in the first pass...

Is it possible to use the passing lamps in the stock chrome housings, or do they offer a chrome housing?
- As far as I know it's only the black compisie housing. However, I did a very quick loo to see if the black housing would fit inside inside the stock HD housing and I beleive with time and patience, you could get the black housing to fit inside the chrome housing. There would be some questions regarding stability of the inner / outer mounting, etc. The other option would be to re-install the stock spots and mount the Bosch units on the engine guard. Saw a quick colution to that as a first option, but wanted the more powerful up high.
On a scale of 1-10. 10 being best. How would you rate them compared to stock. With price, time to install, and overall value all factored in.
I rate each cateory and give some explanation.
Procing compared to stock. Rating : 6. I replaced the OEM spots with the bertical optics spots - $59.95 for the pair. I bought a different set of 110k candle power spots for $35 - lots of light, but also lots of onciming vehicles flipping thier lights. The vertical optic spots have a replaceable bulb, but the only replacement is a 27.5 watt bulb made by Sylvania. They had no "upgrade" for the little 27.5 watt light because f the mounting base. They also mentioned not to use the highr wattage bulbs with the polastic housings. The Bosch units were $51 or $57 each, and the Narva bulbs (H3 35 watt) were $6 each. So - upgrades to OEM stuff was almost $100 and replacement units were $125.
Install time: rating 9. Overall install for both lights was about 30 minutes, plus another 30 min for aiming them. I didn't hurry, and think I stopped for a whiz break and to get a diet coke from the fridge. I did run larger 12 ga wires for the ground wires and this is what took most of the time to make these and connect them to the lower triple clamp and route them. I willspend about another hour upgrading the power side of the the lights, when I get some more time and more details worked out. The reason I'm upgrading the wiring is to minimize voltage drop. There is a tech paper on
www.danielsternlighting.com explaining the difference .6 volts makes in the output of these high efficiency lights. It;s really amazing.
Overall Value: rating 9. I say this is pretty high for a couple of reasons: I tried replacement bulbs in the headlight (Sylvania stuff) and gave them to my son. The Cibie headlamp was $61, Narva +50 H4 bulb was $18, th etwo spots were $114 and bulbs were $12. Add in another $25 for the wire, terminals, Bosch relay, etx.
Dinking around with the OEM stuff, spent roughly $125, plus time and didn't get a positive result. Spent approx $230 on the new setup and and roughly 2.5 to 3 hours with the new items, and I can say for me, the difference is well worth the cost. I have more controllable light where I need to see at night. If I had to put a percentage number on the increase in light, I would say a 100% increase in light.
For me, this is an optimal setup compared to HID because of cost and because of the bluish tint of HID, it actualyy reduces my night time vision. The color of this light is as close to natural daylught as you can get.
I was thinking of going with the new dual bulb headlamp kit from HD. But that sounds like junk. And the new (HID) is too high priced for me to justify and doesn't sound like it's much better.
I know for me, I was skeptical of anything that changed my lighting. The imitation HID stuff was out, HID was out, so I had to look elsewhere. The one thing I found out with this exercise is the guy in Canada told me is absolutely correct. You can have the brightest light bulb, but if the reflector and the lens is crappy, you have a crappy light. This is the reason I'm sold on these Bosch units is because of the reflector and lens. It's a kick a$$ light using only a 35 watt bulb.
The other option I was looking into was using the PIAAH3 & PIAAH4.
PIAA and Hella (and others) make a quality light. I looked at both, but didn't like the light pattern. Both mfgs had a spot light, which had a long range fan type beam pattern (thier passing lamp or high beam lamp) and they both had a fog light type pattern, but nothing that had something inbetween - a long range pattern that had a horizontal cutoff to minimize glare to oncoming traffic.
My bike is a 04 SEEG w/the '05 headlamp in it. I have not heard of any problems with melting the lens w/ high-output bulbs. Is this a problem that should concern me?
Personally, I have never seen the plastic housing melt. I've never heard of one metling, until I did this little prject. I have seen other off-road light I have had on trucks, get so hot, they blister the powder coating when I put higgher wattage bulbs in them. When Daniel Stern mentioned it and then the service rep from Sylvania, someone who sees a lot of them has seen something. I had the headlight in my fatboy with a 100/130 buld get so hot you couldn't touch the housing and that's really close to melting the wiring.
This is one of those projects / topics that there is as much information as misinformation, so if I can help someone figure it out and bypass the 80 or so hours of research I had to do, then that's ok by me. If you get a chance, read the tech info on Stern's website, I quickly found out he is more than an accomplished lightng engineer. He's got the wiring upgrades, aiming procedures, links to x-reference lighting and a ton of info. If you have anhour to read, check out his responses to the NTSB on automotive lighting, it's quite candid for a governmental request for info.
Hope this helps...
