Common Issues of a BMW 328i Tail Light Assembly
Your road visibility at night can be very limited, thus it's of great importance to keep your BMW 328i tail lights in good condition. Normally, your BMW 328i tail light assemblies shouldn't exhibit problems. However, normally doesn't always apply. With that said, below are some common issues that could plague your BMW 328i tail light assemblies.
Dim Tail Lights
Your BMW 328i tail light assembly isn't the problem when you're experiencing dimming with one of the bulbs. Instead, the culprit here is your 328i's electrical system. The system may be burdened with too much work (which can occur when using multiple features of your 328i that require electrical power), thus causing it to supply your tail light assembly with insufficient power. This shouldn't be happening though even if you're using every single feature of your 328i.
Since this issue stems from your electrical system, you should be looking at your car battery or your alternator. Either of the two may already be faulty. Naturally, you'll have to get a replacement for the problematic component.
The bulb on one of your BMW 328i tail light assemblies is flickering? The bulb itself may be a bit loose. See to it that it's securely attached. The flickering should stop once you've done that. If it still hasn't though, the problem may not lie in the bulb but rather in the tail assembly's wiring. Just like in the case of the bulb, some of the wiring may not be properly connected. Fixing this shouldn't be that difficult, of course. However, if there are signs of damage, you'll most likely be left with no other option but to replace the wiring.
Fogged Tail Lights
As you know, a fogged tail light assembly is a safety hazard since fogging can significantly diminish illumination. And if your BMW 328i tail light assembly is fogged, it only means one thing-there's an opening somewhere in there. The assembly may not have been tightly sealed the last time you tinkered with it. There's also the possibility of cracks being present, which may or may not be visible. In any case, you can always wipe off the fogging. But if your assembly is already damaged, it's best to get a new one so that this issue won't come up again in the future.
