Highest wattage headlight bulb fo a standard?

[BigChris99]

I had the shop I took my bike into replace my headlight bulb a week ago. I had them put in another 60/55 watt bulb. This bulb has more of a blue tint to it. It looks nice on the bike, but it is not very bright on the very dark sections of my middle of the night commute home. I know I need an H4 bulb, but what wattage can I go up to without hurting either the wiring or the headlights plastic lens?

My suggestion to you would be to add some DRIVING lights.

Seperate switch on them and a GOOD RELAY.

I have a Cobra lightbar on MGM with these bulbs in them.

The spotlights are GE H7616 they only use 36.5 watts and put out 70000 CP. Lights up the road very well.
 
I don't remember who turned me onto these bulbs.

I picked them up at NAPA about 10 years ago.

They are on whenever the ignition key is on.

Wired them in so when I hit the starter, they go out like the main headlight does.

Also added a very good relay to the system.

The Cobra switch controls the off/on when ever I want them off.

I have them set just a tad high, so as to light up the road a little better.

I know they will let ya spot the forest rats along side the highway getting ready to cross.

I have 100/90 watt that I got at Napa. No problems in 4 years. They make a lot of difference for a little bit of money. I haven't put a relay on them but it's probably a good idea to.

Am thinking the new LED is the way to go. Do a search and take a look at them. Have now seen two on Valks and they are impressive and don't pull anywhere near the current so easier on the electrical system and connections.

I didn't know I could go that high without getting the lens too hot. Good to know. Thanks

I've been running the NAPA 100/80 for 4-5 years now without problems. Lots more light without lots more money. They list it as an 'off-road' bulb.

Here ya' go. Take a look at this thread.

Do you know if a relaunch need to be installed?  Don't know much about power draw but will these compromise the battery reserve?

Should have read "relay".

Have run a 130/90 H4 since 1998.  No problems.  I did power it with relays, and upgrade the bulb socket to a ceramic one.  No heat issues with the lens or reflector.  http://www.horseapple.com/Valkyrie/Tech_Tips/Headlight_Upgrade/headlight_upgrade.html  This bulb is $15.99 at competition accessories at http://www.compacc.com/p/kuryakyn-replacement-headlight-bulbs  If I didn't already have an old-school soln I'd look at the new LED H4's today.
