I'm told that the Cibié ones are better quality than some of the cheaper ones, with better lenses that give much sharper cutoff and better beam definition. I've just ordered a set of 5.75" Cibiés for the inner pair on my 410 to replace the sealed beams, so I shall report back once they're fitted.

Just to update (and I realise that I am here talking about 5.75" units for 408 – 411s2 not 7" units for 411s3 – 603), the Cibié lamps I have now fitted as the inner pair on my 410 are excellent. Good light (I'm using some Philips H4 bulbs) and excellent definition. I have not had any flashing or abuse from other road users, which was a common occurrence with the previous sealed beam units, even though they were correctly aimed according to the MoT station's measuring device. (The car is set up with all four lamps as both full / dip beam, through relays.)
