Front light bulbs are different brightness

Q My car has supposedly failed its MOT due to the fact the front light bulbs are different brightness. One broke and I replaced it with a halogen instead of a xenon. The garage are trying to replace it with 150 new bulbs.

Am I being scammed

Name: Oliver

No - Xenon bulbs are much more efficient and last longer than normal bulbs but they are more expensive.

The MOT manual says: Reasons for failure: An obligatory main or dipped beam headlamp intended to be a matched pair: do not emit light of the same colour are not the same size or shape.

You could always try replacing the other xenon bulb to match the replacement as long as the brightness of the headlamps is sufficient and equal

Q Is it illegal to use headlamps which have a different degree of brightness

The manual states that headlights must be a matched pair A matched pair is a pair of lamps which:

Daytime Running Lights

Q Does a daytime driving light fail an mot if it is not working

Name: Jay jay   Town: Liverpool

Daytime running lamps are not testable unless they replace the front position lamps. Where this is the case, they should dim when the position lamps are switched on and may extinguish when the headlamps are switched on.
