What Size and Type of Bulb Does the BMW 335is Tail Light Use?
The BMW 335is typically uses a 7528 or P21/5W bulb for its outer brake and tail lights, but it’s a good idea to double-check your owner’s manual or look at the back of your bulb housing to confirm the exact fit for your specific year and model. Using the correct bulb keeps your lights working properly and ensures a good fit. If you’re thinking about switching to LED bulbs, keep in mind that you might need extra resistors or error cancellers to avoid dashboard warnings, as the BMW’s system can be sensitive to changes. Always pick bulbs labeled as compatible with your car for reliable, safe performance, and to keep your tail lights looking and functioning just as they should.
How Do I Replace the BMW 335is Tail Light Bulb?
Changing the tail light bulb on a BMW 335is is a fairly simple job. Just open your trunk and find the access panel right behind the tail light. You can usually pop it off by hand, or use a flat screwdriver if needed. Once it’s open, give the bulb holder a twist counterclockwise to remove it. Pull out the old bulb, push the new one in, and then reinsert the holder back into the assembly. Twist it back into place, and make sure everything feels secure. Before finishing up, have someone help you check that the brake, turn signal, and running lights all work. If anything feels stuck or out of place, take your time—forcing things can break the housing or wiring.
Why Is My BMW 335is Tail Light Bulb Warning Light On?
If your dashboard lights up with a tail light bulb warning, it usually means a bulb is burnt out, about to fail, or there’s a loose connection or corrosion in the circuit. Start by checking every bulb and the contacts in their sockets. Even a slightly loose or malfunctioning bulb can trigger that warning. If you’re using aftermarket or LED bulbs without proper resistors, that can also cause the car to think you have a burnt out bulb. Once you find and fix the issue—whether it’s changing out the bulb or cleaning up a corroded contact—the warning light should go away. You might have to reset it depending on your model.
Can I Upgrade My BMW 335is Tail Light Bulb to LED?
Upgrading to LED tail lights is a popular choice for BMW 335is owners who want brighter, longer-lasting bulbs. While you can make the swap, BMWs are known for their sensitive bulb monitoring systems. So it’s important to use error-free LEDs or install load resistors to avoid warnings on your dashboard. Always check that the LED fits your housing and matches the car’s voltage needs before putting it in place. LEDs offer crisp, modern light and often last much longer than regular bulbs, but make sure they’re road legal in terms of brightness and color, and install them carefully to avoid any wiring or housing issues.
What Should I Do If My BMW 335is Tail Light Bulb Keeps Burning Out?
If your 335is keeps blowing tail light bulbs, there may be an underlying problem. Check the tail light assembly for moisture, as even a little water can cause bulbs to burn out quickly. Look at the sockets for signs of corrosion, heat marks, or loose fitting. Using the wrong kind of bulb, or one that's too high in wattage, can also cause frequent failures. Rarely, the issue could be an electrical problem like a faulty wiring harness or voltage regulator. If new bulbs keep failing after checking these things over, it might be time to have a professional take a look, just to be safe.
