Hi! I'm not familiar with the exact light setup on your model - I drive a '64 PV544, which had the worst lights I ever had on ANY car!

The above information on checking and cleaning the terminals and checking the charging voltage is exactly where you want to start. You can skip checking all the terminals if you have good charging voltage and you also check the voltage at the plugs on the back of your headlights. They should be a minimum of 12V and a maximum of about 14V with the engine running. If you get less than 12V at the headlights, by all means, go back and check all those terminals and the switch!

From the 1st reply, I'll assume you have round 7" headlights instead of the rectangular plastic ones.

Inspect the front of the headlights. If they don't both say HALOGEN in the middle, you have really outdated incandescent headlight bulbs and need to upgrade to at least Halogen lights. That should just about double the output.

If you want ot go a step further, find a set of 7" round headlights that accept an H4 bulb. The stock headlights don't have replaceable bulbs, but there are many units on the market now that allow you to insert different bulbs into the glass housing.

I paid about $25 for a pair of those glass housings on eBay. If you decide to go this route, buy the housings that have the same look of multiple tiny lenses on the front that the stock ones do. The 'diamond' style light housings look nice but they don't focus the light that well.

Now, the REAL upgrade to your lights comes when you exchange the stock H4 Halogen bulbs for H4-style XENON GAS bulbs. I buy only Toucan Eurolite Xenon Fusion bulbs and I get them on eBay, although I have seen them in stores for a little more money. The Eurolite Xenon Bulbs put out about twice the light of Halogen lights, but they don't blind other drivers if you have good housings and the headlights are aimed properly.

From the driver's seat you'll notice the difference immediately; it's almost like adding aircraft landing lights to your car! The light has a blue cast to it, like the expensive HID units on import luxury cars. The blue light is very close to the color of daylight, and everything is much clearer and more visible.

Note that Phillips Silverstars are also Xenon Gas bulbs, but they will cost you 2-3 times as much as Eurolites, and I don't like the light as much.

If by some chance yo have the plastic headlights, you'll want to buy some Rubbing Compound in the car wax section at Wally WOrld and polish the housings until they are clear and look like new again. Ultraviolet light quickly degrades the Lexan plastic that is used to make those housings, leaving them murky. Use ArmorAll or 303 Aerospace Protectant to help reduce the UV damage after you clean them up.

The plastic headlights already accept replaceable bulbs, so all you'll need to do is to determine which style bulb (9005, 9006, 9007) your car uses and go from there.

As you can tell, I'm a HUGE fan of Xenon Gas lighting!

Good luck, and please come back and let us know how you cured your problem!
