Have seen a few companies selling these, eg ionic dynamics, interior innovation etc, etc

Can someone guide who sells the best quality/ fit versions?

Thanks

Carmad has some, don't forget his, fit is not too bad either, cannot vouch or discredit the others.

Thanks, I notice that Z centre no longer do these, part of me does wonder if doing the 99 spec inserts is actually worth the effort!! Might just chrome the standard inserts and go with that... afterall they will never create the same effect as genuine 99 seconds headlights.

You will never create the same look without great expense, I'd just stick with the oem charcoal 89 insert, there's nothing wrong with them. 

Yes think i'm gonna knock the 99 spec inserts on the head, maybe concentrate my efforts on a bi-xenon conversion with new projectors makes more sense
