Having recently heard of the new law requiring the use of one’s headlights when operating the windshield wipers, my concern is of remembering to do this consistently. Is it possible to modify my “96 Accord to do this automatically?

June Taylor, Winters, Calif.

More than a dozen states have passed legislation requiring the use of vehicle headlights during conditions necessitating the use of windshield wipers or when there is reduced visibility.

Can your Accord be modified to do this on its own? Sure.

I haven’t yet found a wiper/headlight retrofit kit on the market, but they’re sure to come soon.

A sharp and willing automotive electrical shop also could create such a kit, using a sturdy relay or two, a pair of fuses, some wire and the right electrical connections.

The simplest solution is to purchase a daytime running lights kit and have a qualified technician install it.

The better kits run about $50 and require only three electrical connections – power, ground and low-beam headlights.

The DRL module’s internal circuit senses charging system voltage and turns on the low-beam headlights only when the engine is running.

Can such a kit be installed by a do-it-yourselfer?

Yes, but my concerns are of the variations in headlight circuitry from one brand of vehicle to the next and of prudent and skillful connections and wire routing.

Even though the DRL circuit parallels the original headlight circuit, an accidental short to ground could affect headlight operation – very serious business indeed.

What’s the best way to cure squeaking belts? Mine really sound off for a few minutes each morning.

Belt noise can occur for a variety of reasons: a glazed friction surface, contamination, improper tension and incorrect pulley alignment. Start by checking your belt(s) for excessive looseness.

This is far more of an issue with individual V-belts, as the automatic tensioner used on single, serpentine belts generally does a good job.

If a belt shows more than superficial and infrequent cracking, glazing or oil contamination, it should be replaced.

Pulley alignment also might be the culprit, particularly with a serpentine belt.

A replacement alternator or other belt-driven accessory might mount up slightly fore or aft, or be cocked at an angle, causing the belt to distort as it passes through the pulley.

What about spray-on belt dressings? In my opinion, they’re a short-term solution that covers up the real issue, and can make a bit of a mess. My favorite replacement belt is the Goodyear Gatorback. They run more quietly and offer better longevity.
