What are your thoughts or recommendations for headlights on my ‘66 truck? The stock lights are just not too bright........ I don’t need super bright just a little better then I have Now.

The problem may be with your truck, not the lamp. Dim headlights could mean a problem with the wiring somewhere. Check the connectors at the back of the lamps for corrosion and partially broken wiring. The wiring for the headlights also goes through the dimmer switch and light switch. If any of them has excess resistance, then the light can be dim. It's less common to have issues with those connectors, but it is possible, and the switches themselves can have excess resistance.
To check, turn on your headlights and measure the voltage at the connector at the back of the lamp. A good resource is below.

I installed relays for my High and Low beam circuits and wired them directly from the battery terminal at the horn relay. For the power circuit I used 14 gauge wire. That improved the brightness greatly. Then I installed Halogen replacement lamps.

I will definitely check out the wiring. What lamps are you using?

I bought the ones from LMC. they have a housing that fits just like the original sealed beam and a handy little socket in the back where the lamp screws into. I have blue lamps for it too but I have never installed them.

L.E.D. lights are supposed to draw less power. Without fixing the lower power problem would they be a lot brighter than stock?

LED lights do draw a lot less power. Because of that, the voltage drop at the light will be less and it can mask some minor wiring issues. They should alleviate the need for relays and upgraded wiring, but I would still check the factory wiring for frayed wires at the connectors, especially at the back of the lights.

Yes, but a set of LED headlights that are actually useful instead of just gimmicky junk, will set you back quite a bit of coin. There's really only one company I would trust for this and that's TruckLite; Maxxima also offers one but I feel their quality is a little lacking. Both are well-known suppliers of LED (and traditional) lighting for fleet vehicles.

http://www.truck-lite.com/webapp/wcs/stores/ser vle...

The TruckLite examples for the 7" round are about $160-$170 each, but they're very bright, are DOT compliant, have a 3 year warranty...and should last practically forever.

http://www.maxxima.com/products/27/LED-Headl amps.h...

Maxxima offers a 5 year warranty but I feel it's an attempt to gain market share over TruckLite. I've had so-so results with other Maxxima LED products. They're OK; just not great. The 7" round LED headlight is priced near the same as the TruckLite offering.

Good stuff! thanks Richard!

Personally, I don't think I would go to LED head lights on my truck. I get the performance I need from the halogens and I'm upgrading the alternator anyway because I have an electric cooling fan and fuel pump so the difference in overall draw isn't consequential. I've already resized the feeder conductors to the headlights so everything is good design wise.

My gripe with them is they have such a funky look and I think would spoil the appearance of a 60-66 truck (or any classic truck for that matter.) I dig technology when it delivers on its promise, which frequently it does not...but in this case even a good product like these TruckLite LED's, I see them fitting in better on modern heavy equipment that still uses a big round headlight. When you put it on a classic, even one that is a resto-mod, it just looks...wrong...to me. I don't care for the replacement housings that let you pop in a modern halogen headlight capsule in the back, either.

I'm with Richard, they just wouldn't look right on our older cars and trucks.

I upgraded the wiring, sockets, added relays, and upgraded to HID bulbs with Bosch lenses. They look almost stock, work fabulously, and I can see better than ever.

Here's a link to the thread on it:

http://www.chevytalk.org/fusionbb/showtopic.php?ti...

NOTES:

1. The link to the picture of the Bosch lens assembly doesn't work. The Bosch # is 301 600 118, and you can look it up on eBay or Google.

2. I used 35W, 4300K Bi-Xenon bulbs. They are not that awful blue you see all the time these days. VERY white!
