How to Change the 5 Most Neglected Auto Light Bulbs in Your Vehicle

The auto light bulbs that burn out most often are the taillight, stop, turn signal, backup and headlight bulbs. But there are many other bulbs in a vehicle that could use your attention, too. These are the five most commonly neglected bulbs that can affect your driving experience. Check yours to see if they work, and pick up replacements at any auto parts store.

Tips For Changing Auto Light Bulbs

We’re not going to ask how many DIYers it takes to change a light bulb. But did you know there are a few tricks to changing the bulbs in your vehicle? Read the following tips and file them away in your long-term memory.

1. Check the bulb for signs of tungsten filament deposits. The darker the buildup, the closer it is to burnout.

2. If you’re replacing a bulb in an exterior socket, apply a very light coating of dielectric grease to the bulb’s contacts. That’ll prevent corrosion.

3. A long-life bulb is worth the price. It’ll last at least twice as long as the original, so you’ll most likely never have to replace it again.

4. A “blue” bulb (Sylvania SilverStar is one brand) gives off whiter light, making it easier to see in the dark. Use them for dome, map, fog, and backup lights.

5. Always wear gloves when you handle bulbs. Skin oils can cause bulbs to swell and fail. It’s especially important to prevent swelling on headlight and fog light bulbs. But skin oils can also cause miniature bulbs to swell and fail.
