One Headlight To Bright

[Fish the Mod]

recently purchased a second hand Renault Megane and the offside headlamp is brighter (full beam) than the nearside ( others drivers keep flashing) I changed the bulb and made sure it is the correct one but its still too bright. Any ideas why

[Everhelpful]

Probably your lights need adjusting.

Needs adjusting maybe!

[Bazile]

how do you adjust the brightness ?

[Baldric]

You don't Baz, you lower the angle of the light which has the effect of making it look less bright to oncoming traffic!
(as if you didn't know)

Are you sure that you mean full beam and not dipped beam ?.

[Hopkirk]

If the bulb isn't seated properly it can sit in the wrong place for the reflector, and shine too high.

I agree with Tonyav, do you mean dipped? If you mean full beam, then no wonder drivers flash you!.

[Hypognosis]

I wonder if it's had a shunt and someone has put in replacement glass from a LHD vehicle - which then throws the light to your right and into the eyes of oncoming drivers? Bit of a long shot but worth looking closely and comparing with other local Meganes.

Only other things I can think of are to take out both bulbs and look closely at design/serial numbers to see if they're a matched pair.

While they're out, compare the fittings. There should be a 'right way up' and tabs which stop you fitting the bulb upside down.

Lastly, is there an adjuster wheel on the dashboard to control the amount of dip according to how many persons on board? (Stopgap adjustment while you sort out a permanent fix).
