I drove my car the other sunday night for first time in over 18 months and i didn't have drama's with the lights, i've got a magna as a daily driver and i have to say that the lights were just as good as the magna...
As for alternators, apparently the drama's with the standard dr one's is, being internally regulated they can't keep up, yes there is a bosch alternator that does fit, Josh has swapped to one i don't know which one it is, but i know there is some wiring that has to be changed going to it but apart from that is a direct fit
