Just fitting morrette's on my 2001 bugeye and they work fine on dipped beam. When I put them on full beam they work but not at full brightness. Anyone had the same problem?

 

Have you used relays or are they just wired into the original loom ?

Using the one relay that they were supplied with.

 

Check the earth path from the mainbeam bulbs.

Is it thick enough wire? (Is the feed to them thick enough too??)
Is it connected to a suitable earth point, or, better still, back to the battery? Does it make good contact?

If these are OK, then put a voltmeter onto the output, (terminal 87) on the Morette relay, and check voltage with engine running, it ought to be somewhere over 13V.
If it isn't, check all feeds to relay, connection of +ve to battery, and relay, and finally suspect the relay.

If you think it might be the relay, connect the lead from terminal 87, direct to the lead from terminal 30. The mains should come on, and they ought to be bright.

Thanks for the help Alacazar, I'll give it a go at the weekend and let you know. Cheers.
