The H4's in my 41 Willys are simply terrible. The low beam is about 10 feet out and the high is barely low enough to keep oncoming traffic from blinking me. Plus they are dreadlfully dim. these are brand new H4's too. The stock lens seems to block and disperse the beams. I asked the supplier about the reflector and he claims it is correct.

Are the Sylvania super bright or whatever they are called any good?? They are about $35 each instead of $10. I hate to spend $70 for nothing.

The fix I'm told is to run both high and low beams on high beam and just the low beam on low. This also requires 2 relays and heavier wire to the H4's. It sounds easy untill you get to the hardware and actually running the wires.

If you run relays with your existing lights it should make a big improvement,it is fairly EZ to do click on this for an EZ explanation: www.watsons-streetworks.com/current_topic.html

Here's something you might want to read before you buy any more H-4 bulbs. Also - relays work best. You can run wiring that will handle the 55 or so watts rather then the 16-14ga usually supplied in a kit.



Oh - and the Sylvania super bulbs - they are, but you will give up lots of their life expectancy for that extra brightness. That's from personal use as well as many reviews I've read.

The H4 is only the bulb.
The headlamp optics (reflector, lens etc) is critical to correctly focused lamp.
And of course proper aiming.
These work great. Hella 70 477 is the 7" round assembly. Not cheap but ----
All other parts of electrical system must working correctly especially the alternator.
Wire size to the lamps #14 or larger. Good grounds. Quality headlight switch. Quality dimmer.
I see several internet sites that sell them. Also try e-bay.

The Sylvania Silverstars are bright, but kinda expensive.

Well I have the shop on weekends for the next few weeks so I think I'll try the relays and heavier wire first, then if there is some improvement I can just add the Sylvania lamps. Fortunately the lens are glass.
