Correct answer
avoid touching the bulb glass with bare fingers.
Avoid touching the glass with bare fingers. Grease left on it can heat up and damage a halogen bulb; this specific precaution does not concern its metal terminals. Work with the lights off and the bulb cool, following the manufacturer’s instructions and using suitable clean gloves. Not every replacement legally requires a workshop; seek professional help if you cannot do it safely.
