How to Replace a Long Tube Light Bulb?
3 Answers
Turn off the power and disconnect the switch. Hold both ends of the tube light with your hands, about 10 centimeters from each end, and rotate it clockwise about half a turn. Align the two copper pins inside the notch at one end of the tube light so that the two pins and the plane of the clip are on the same level. Pull the double pins downward from the notch, then remove the other end.
Replacing a long tube bulb is actually not difficult; I've done it myself several times before. First, turn off the engine and let it cool for a few minutes to avoid burns. Open the hood and locate the position behind the headlight assembly, where there's usually a wire socket plugged in. Gently pull out this socket—remember not to yank the wires, as damaging them would be troublesome. Next, check how the bulb is secured—it might be a rotating base or a clip. Carefully unscrew the clip and remove the old bulb. When installing the new bulb, avoid touching the glass part with bare hands, as the oils from your skin can damage the bulb. Wearing gloves is best. Align the bulb with the base, secure the clip, and plug the socket back in. Finally, test the light to ensure it works before closing the hood. The whole process takes about 10 minutes, saving you the $200 labor fee at the repair shop. Remember to regularly check bulb lifespan, especially before long drives, to avoid sudden failure at night.
I take extra safety precautions when replacing long tube bulbs. After preparing tools like gloves and screwdrivers, first ensure the car is parked on level ground with the parking brake engaged. Turn off the engine and wait for it to cool before opening the hood—don’t rush to avoid battery short circuits. The bulb location may be hidden; use a phone light to clearly identify the socket. Remove the old bulb slowly to prevent glass shards from scattering. Always buy OEM-matched bulbs—avoid cheap off-brands, as they may be less durable or cause circuit issues. When installing, ensure proper orientation and test the lights before securing them. If you’re unfamiliar with electrical work, consult a professional to avoid shocks or damaging other components. Safety first—saving a little money isn’t worth the trouble.
