bulb adapters

Where can i find the adapter rings for the h4 bulbs.

Here.... but you really don't need them.  After breaking off two tabs off an H4, and installing the bulbs in the interstate, they stay put, and didn't need re-aimed either. I have them and would have reused them, but it was hard enough just getting the bulbs alone in... I could not get the bulbs and rings to line up together and go in.

I have got to take my fairing off this winter and repair a crack and though i would install them perminately when i had it apart.

Well, I think they may only be as permanent as the bulbs you choose.

I could be wrong, but think they must come out with a bulb replacement.

Using the reach in and grope around blind method I have used, getting them (and the bulbs) out is easy; getting them poked back in is the tricky part.

With the fairing off, everything is easy.

On the upgrade side, many have used the 60/55 H4 Silverstars (and some others) which are brighter than over the counter auto parts H4s, but are often reported as only lasting a year.  I ordered some off-road 80/100 and 90/100s off Amazon, and put them in my two interstates over three years ago and they are still going strong (a bit more expensive than std 55/60 H4s, but much cheaper than Silverstars).  I don't do much night riding, but aimed properly I have never been flashed at night on dims.  Because the IS fairing breathes so well, there have also been no reported socket or wiring heat problems with these off road bulbs... none with mine either. 

With a std/tourer, changing the bulb is easy.  It's not so easy on the IS using the reach and grope method, so bulb longevity is more important (to me). 

Read the reviews (scroll down).

I seem to remember be warned off the Optilux bulbs (for lack of brightness, not longevity).

After you repair your fairing you NEED to still be able to change bulbs. On JUST a bulb change on an I/S loosen all 4 bolts-roll fairing forward and either snug lower bolts or use a tarp strap to keep fairing rolled forward. Just rolling the fairing forward makes room for old arthritic fingers that ain't near as nimble as they used to wuz!  RIDE SAFE.
