Clean the Inside: If there are contaminants inside, you might need to disassemble the headlight, if it's designed to be taken apart, and clean it.

4. Reassemble and Test Reinstall the Headlight: If everything looks good, reassemble the headlight and reconnect it to the vehicle. Test the Headlight: Turn on your headlights to ensure they are functioning properly.

5. Replace if Necessary If the bulge persists or if the headlight is cracked, it may be best to replace the headlight assembly with a new or good-quality used part.

Additional Tips
