Diagnosing Common BMW 330i Headlight Bulb Concerns
Your BMW 330i headlight bulb is a xenon bulb that performs better than regular ones. Without it, you're left with a luxury vehicle that has diminished safety features-pretty much a useless car. Although BMW parts are among the most durable parts there are in the market, a headlight bulb can still become damaged in time because of constant use and exposure to weather elements. BMW cars are luxurious, but they still require basic repairs like any other car. Here is a guide to help you diagnose and troubleshoot common problems with a headlight bulb:
Unusual heat coming from the headlight housing
Your BMW 330i comes equipped with HID xenon headlight bulbs, which normally don't generate a lot of heat as they use inert gases to control the bulbs' temperature. However, over time and with constant use, headlight bulbs are also bound to overheat. In this case, visual inspection is ineffective-the headlight bulb can still give off light normally, causing you to think that nothing is wrong. Instead, check for wear or damage in the bulb socket-a damaged socket will most likely cause improper heat dissipation. Inspect the wirings for any loose connections or exposed wires. Check if the parts exposed are in contact with other metal parts under the hood. Improper insulation can cause an increase in heat to the light bulbs.
Flickering headlight bulbs while driving
At times, a bulb can come loose after a long drive, and this might be what's causing the headlights to flicker while you are driving. Check if the bulb is sitting snugly on the socket. If it is loose, make sure to tighten it enough so that it doesn't rattle and bounce when you are driving. The bouncing motion is what's causing the bulb to intermittently touch the contacts in the socket.
Headlights won't turn on at all
You switch on your headlights and you notice that the left one won't come on at all. You drive around with a busted headlight, hoping a traffic enforcer won't notice. Then the right headlight fails as well. This could be a sign that the headlights' service life have ended. Check for a busted fuse or faulty wirings as well.
Wonder what happens when you don't take care of your BMW 330i headlight bulb regularly? It will give up on you right in the middle of the night on a dark road. The thought is made scarier when you realize this could earn you a ticket for a violation-it's illegal to drive around even with just one busted headlight. A failing headlight bulb will turn a bluish or purple color for a couple of weeks then start flickering. Worse, if you ignore the problem, your headlight might turn on, flicker for a few seconds, and then stop working altogether right when you need it. To help maintain your headlight bulb in tiptop shape, here are a few tips you can follow:
Keep your headlight bulb clean.
When replacing a headlight bulb, make sure you use a glove to hold the new bulb. Fingerprints left on the bulb can heat it up faster than normal. Cloth fibers can also cause the bulb to heat up faster, making it last shorter than its service life. Use a microfiber cloth to carefully clean the bulb, making sure not to pinch it too much as it might break. Make sure it is free of moisture as well, as moisture can multiply the heat given off by the bulb.
Switch your headlights off in the daylight.
This is something that you might overlook when you are too busy keeping your eyes on the road. Keeping the headlights on while there is still daylight will diminish the service life of the bulbs.
Make sure your headlight bulb is sitting securely on the socket.
A loose fit on the socket can cause the bulb to work intermittently. If the bulb does not stay in contact with the socket, it will not get the required power it needs to maintain a constant light. This can cause the bulb to flicker when you are driving, and eventually its ballast will wear out because of the irregularity at which it gives off light. When cleaning and inspecting the headlight assembly, gently turn the bulb clockwise until it fits snugly on the socket.
