Maintaining a classic car's lighting system is an important part of keeping the vehicle safe and functional. Here are a few tips on how to maintain classic car lighting systems:

    : Make sure to check all lights on the car, including headlights, taillights, turn signals, brake lights, and license plate lights. If any lights are not working, replace them as soon as possible.

  • Over time, dirt and grime can build up on the lenses of the lights, reducing their visibility. Clean the lenses regularly with a mild detergent and water to ensure that they are clear and bright.

Toothpaste and baking soda both have the potential to be useful cleaners when it comes to headlights. Both chemicals are sufficiently abrasive to remove fog from headlights without damaging or scratching them in the process. There is also a possibility that polishing chemicals such can be effective enough to repair UV damage.

  • Check the wiring of the lights to make sure that it is in good condition and free of any damage. Using a multimeter and the wiring schematics for the vehicle , it is a simple task to check for damaged wires in the vehicle and even to discover the break in the wires themselves.  

Without access to a device that can test for audible continuity, it is  possible, but more complicated , to  make use of the lowest Ohms scale and search for resistance lower than one Ohm.

If the wiring is found to damaged, replace it or have it repaired by a professional.

  • Make sure that all bulbs are working properly. Dim headlights, side lights and even rear lights are one of the first signs that a headlight bulb is malfunctioning or has become defective. It is possible for headlight bulbs to become worn out over time, causing them to emit a light that is noticeably dimmer than when it was first turned on.

A dim headlight will not give adequate illumination, and it is also typically a warning that the bulb's service life is getting close to its conclusion.

Regularly inspect the bulbs for any visible signs of damage and replace any that are not working.

  • Make sure all electrical connections are clean, tight and not corroded.

It is possible to rapidly trace the cause of an electrical issue in a classic car by

turning off all of the circuit breakers and then put a bulb that is already turned on into one of the outlets. To get the lamp to light up, the breakers must be turned on and off one at a time. Plug the lamp into each of the other outlets in the immediate area to find out which ones are connected to the same circuit.

    • Make sure that the headlights are properly adjusted so that they illuminate the road ahead without blinding other drivers.  The vehicle’s manual should be consulted if available, if not – an auto -electrician should be consulted.

    • As a matter of courtesy to fellow drivers as well as general road safety, check that the headlight dimmer switch is working properly and smoothly switching between high and low beams. Dimming systems typically come with pre-sets that, once activated, require only infrequent tweaking.  Preventing system difficulties by locking them either mechanically or electronically will also do the trick.
