Tools generally needed to install BMW 330i Tail Lights
- Socket wrench set or Phillips screw driver
- Painters tape to prevent scratches to your BMW 330i
- (Rare) Torque wrenches, etc.
BMW 330i Tail Light installation procedure
- Inspect the new set of BMW 330i tail lights to make sure you can complete the installation with the tools you have available.
- Disconnect your BMW 330i battery's negative battery terminal. If your stereo requires a key in order to reboot, please be sure you have it before disconnecting the battery. Also, be aware that you will probably have to reset your clocks, etc. after reconnecting the battery later. Please note that some vehicles (such as newer GMs) have extremely sensitive electrical systems. In these cases failure to disconnect the battery before attempting installation may lead to blown taillamp fuses or other damage.
- Apply painters tape on your BMW 330i around the edges of your 330i's taillights to prevent any scratches that might occur while removing and installing taillamps. If uninstalling your BMW 330i rear bumper is required, make sure you have a safe surface to place the 330i bumper on and that the working surface below the vehicle is also safe in the event the bumper falls down. This step is particularly important because tail lens, unlike headlights, often require a little force to come loose, leaving many people to inadvertently scratch their BMW 330i in the process.
- Without touching the glass, uninstall the stock brake, signal and reverse bulbs (as applicable). For bulbs with flat rectangle harnesses, you just pull the bulb firmly outward. For bulbs with round bases, you usually just push them in a bit, and then turn a quarter turn to release them. Once the bulb is removed, place them in their original container (if available). If they are cold, you could also store them in a ziplock type of bag. Please note that if your BMW 330i tail lamps have a harness that can be separated via a main harness that leaves part of the harness with the bulbs inside the 330i tail lights, you will still need both parts of the harness since the aftermarket BMW 330i tail lights are designed to either re-use the stock bulbs (altezzas) or to connect directly into the bulb harnesses (LED taillights).
- Unscrew the BMW 330i taillamps from the front or use a socket wrench to undo the 330i tail lamps from the back. Be aware that the old BMW 330i tail lights might fall immediately once the tension of the bolts is removed. For this reason, it is best to lightly hold the lights in place with your free hand as you unbolt or unscrew them.
- Remove the old BMW 330i taillens and store in a way that the lens will not be scratched. Install the new BMW 330i tail lens and bolt / screw in place.
- BMW 330i LED Tail Lights: Some of your stock bulbs, such as the reverse lights, might be re-used in your new 330i LED lights. For the rest, the LED lights will come with male plugs that should be identical to the ends of your stock bulbs. Connect these into your stock harnesses. For plug in type harnesses, please try to install the plugs in the opposite orientation if they do not work.
- BMW 330i LED Tail Lights: Since BMW LED taillights operate at a lower wattage than your stock bulbs, they include a resistor in order to regulate the current being passed to them. While sometimes this box is internal, more often it is external and connected via a plastic plug. In the case of an external resistor box, it needs to be mounted somewhere (they usually have double sided tape on the backs) where it will be away from heat and moisture.
- Reconnect your BMW 330i battery and turn on your BMW 330i taillamps and check for proper operation and blinking speed. If any functions are not operational, try flipping the plugs the reverse orientation and double checking that the resistor boxes are fully connected.
- Reconnect all connections and tighten all bolts in place.
Are these BMW 330i tail lights sold by piece or as a pair?
All our BMW taillights are sold in the full pair. When you pay the listed price, you receive the complete set including both the right and the left sides.
Are these BMW 330i tail lights street legal?
As far as we know the Sonar (aka Spyder) and KS (Anzo) brand tail lights on our website are all street legal as mandated by federal law in the United States. This basically means that they are designed to the specifications set forth by the DOT (United States Department of Transportation). Occasionally, DOT might test models for compliance. If any BMW 330i taillights fail (rare) DOT will have the companies issue a recall. For those tail lens, you can return them to us for a refund. For any other brands besides Sonar (aka Spyder) and KS (aka Anzo), we can not guarantee DOT compliance. Also, please be advised that your local laws that may disallow these sorts of taillights to be used.
After I installed BMW 330i LED tail lights my front signals are blinking fast. What do I do?
Your BMW 330i front and rear signals are connected, so when you have a problem with one you will have a problem with the other. A fast blinking signal usually points to too much wattage going through the system. This can be caused by three different situations: 1) a dead bulb in the front or the rear, 2) the appropriate plug on the LED taillamp being plugged in upside down, or 3) the resistor box not being connected or malfunctioning.
Dead bulbs can be examined by eye for blowouts. If one of the wires is broken and/or you see a burnt part of the bulb, then it is probably dead. For the LED plugs, this would only be the case if they were ALWAYS blinking fast. To remedy that situation, just unplug and replug the bulb in the opposite orientation. For a defective resistor box, check the connection. Worst case, try the resistor box from the other side to isolate the problem.
How can I prevent my BMW 330i tail lights from fogging up?
During the first few days of operation, it is normal to see some moisture appear in your BMW 330i tail lens. This is due to the small amounts of moisture in the plastic and coating that are evaporated when the tail lens are first warmed up during use. This sort of moisture is normal and should disappear within a few days.
To be sure that no external moisture gets into the new BMW 330i tail lens though, it is a prudent idea to silicone seal the edges. Clear silicone sealant can be found in any hardware store (and some auto part stores), and can be applied to the seam along the 330i taillights where the clear lens meets the rear housing. Also, even if a bulb has died, make sure to keep it installed in the 330i tail lamp until you replace it to prevent moisture from entering through the bulb hole.
Can I smoke my BMW 330i tail lights?
While smoking your BMW 330i taillights (tinting them) is certainly possible through the use of carefully applied spray tint (use light even coats), doing so may make them too dark to be legal. Please check your local laws as well as smoked BMW 330i taillights of any darkness might be illegal in your area.
