How to remove the brake light bulb of Bestune X40?
3 Answers
The replacement procedure for the Bestune X40 brake light bulb is as follows: 1. Open the engine hood. The release button is located below the lower right side of the steering wheel. Press it to open the hood, then reach into the engine compartment slightly left of center towards the GS and pull the release. 2. Unscrew the screws and fasteners. 3. Remove the dust cover of the headlight. The dust cover is made of flexible rubber and can be removed directly. 4. Rotate the halogen bulb counterclockwise to remove it. Be careful when handling the bulb - ensure it's not hot before removal. 5. Screw the new bulb back in clockwise.
I've personally replaced the brake lights on my Bestune X40 several times. Here's a simplified step-by-step process: First, open the trunk and locate a black plastic cover panel on the inner side of the taillight. Use a Phillips screwdriver to remove the two securing screws, then carefully remove the cover. This will expose the bulb socket - the brake light is usually the outer bulb with dual contacts. Pinch the socket and rotate it counterclockwise about 30 degrees to remove the entire assembly, then pull the old bulb straight out vertically. When installing the new bulb, avoid touching the glass part with bare fingers to prevent oil residue that could shorten its lifespan - wearing gloves is recommended. Align and firmly insert the new bulb, then reassemble the socket in reverse order. Always test the brake light before reinstalling the cover. The whole process takes about 20 minutes, and the key is getting the correct bulb model - P21W.
Last time I helped my buddy replace the brake light on his Besturn X40, I discovered a little trick: The cover panel near the trunk taillight is actually connected with clips, so don't yank it hard after removing the screws. When taking out the lamp holder, pay attention to the rotation angle—I've counted and a quarter turn works best. A common mistake is accidentally removing the entire taillight assembly when you only need to work on the lamp holder part. For bulbs, I recommend brand-name parts like Philips, which cost way less than dealership prices. During installation, a 'click' sound means it's properly seated. Always test the brakes afterward, preferably in a dimly lit underground garage for better visibility. If doing it yourself, prepare a Phillips screwdriver and a clean cloth in advance to avoid dirtying the lens.
