60/55 Watt H4??

[Louis Durocher]

Is there a problem to put two 60/55W Bulb instead of two 45/45 on my I/S?

[Momz]

No, your altenator is more than up to the task.
I can not remember what the wattage is, but I've been using Sylvania Silver Star H4 bulbs in my I/S for years now.

No  problem at all and you will like the additional light output.  They give  significantly more light without being so bright that they wash out the reflective street signs so you can't read them.  Been running them for several years.....I use the automotive version which most folks use a little adapter ring available on ebay and you need to cut off the tabs on the new bulb for the ring.  Don't get your fingerprints on the bulb glass....

Been running auto H4's for years.  Honda's are only different in the base, to jack up the price of a bulb.  And you do not even need to use the little holder rings (at least not on the interstate).  Even after bending/breaking off the tabs, the bulbs stay in place just fine, and do not lose position relative to the housing reflector at all.

I tried to use the rings with new bulbs in my interstate (without taking the fairing off), and I could never get everything lined up reaching up into the little holes.  I've never needed the rings at all through multiple bulbs.

Is it 60/55 you are using? without a relay?

The Interstate headlight circuits already have relays.

[Jess from VA]

Yes the IS already has relays.

And, after using 55/60s for years, I installed pairs of off-road 80/100s and 90/100s H4s in my two interstates a few years back, and they have been a great improvement, and I have no heat or wiring or socket issues whatsoever.  The IS fairings really breathe well (unlike a std/tourer bucket).  I run dims all the time, rarely run at night, and have never been flashed on dims day or night.

This should not be done in a std/tourer bucket without upgrading wiring, socket and relay.  MarkT has the information on such an upgrade (and has posted it here before).

I have been using 60/55 Watt H4 bulbs for the last 5 years. Never had a problem. Paid 10.00 ea at Canadian Tire. I had to adjust the beam angle down a bit due to increased brightness. Cars were flashing their high hi-beams at me.

Like I said before - plenty of cooling in the std/tourer bucket.  In fact I clean bees etc out of the wiring in there when I open it - they come in through the large gap around the ring while the air flows on out the big hole in the back.  I run a 130/90 H4 bulb in mine and have since '98.  No heat damage at all.  My wires are upgraded with relays and the socket is high-power too.
