New vehicles have complex headlight systems that make switching bulbs more difficult. In many models, you must remove the entire lens assembly to get to the bulbs. This is often a frustrating issue because when you buy your car, you are told the new technology is also supposed to help bulbs last longer. That is why it gets frustrating when you constantly have to visit your auto mechanic in Madison, TN for light changes. However, there may be other things going on to make your headlights not as reliable as they once were. Here are four issues that go wrong with headlights:
- Water and condensation: One of the main reasons headlights burn out frequently is the buildup of water and condensation in a lens. This causes small shorts that even the best LED lightbulbs cannot withstand. The result is constant bulb changes without addressing why it happens in the first place. If you face this situation, ask your mechanic to look more carefully. Many times, we need to replace the lens assembly, so they are once again sealed from the elements—and keep water out. If you notice fogging on your lights, this is likely the cause of your burned-out headlights.
- Bad installation: The key to installing auto lightbulbs is to avoid touching them. New LED lights are especially sensitive, and if you handle them incorrectly, they are likely to be burn out soon due to the corrosion caused by your skin oils. If you replace head lamps at home, handle them with a paper towel or wear latex gloves. At the very least, be careful to only touch them on the plastic base. That will keep them from being damaged by your hand oils during installation and will help them last longer.
- Rough roads: Lens assemblies are hardy, especially the ones installed on four-wheel-drive vehicles, so this is a less common cause of lightbulb burnouts. However, occasionally a rough drive on an unpaved road can dislodge lightbulbs and disconnect wires to literally turn out the lights. The same rough drives can also damage them to the point they require replacement. Sometimes, if there is something else going on, like corroding wires or lens assembly issues, all it takes is a bad hit on a pothole to damage bulbs.
- Electric issues: Older vehicles may burn out headlamps due to failed electric systems. Worn out wires, constant shorts and loose lens assemblies may lead to constant bulb failures. In these cases, it is more likely that a rough road or pothole will lead to a lightbulb requiring replacement. If the burnouts are frequent and you notice other electric issues going on, it is likely a system problem. We will need to investigate and see where wires need reattachment or replacement, so you do not face this ordeal again.
