len your a stubon ole sod!!
if you flash hids, they will not blow! there are no filaments in hids, the have zenon gas and are ignited by a high voltage ballast and then they burn which makes them light up, they last longer than halogens because there are no filaments to burn out, the only downside to hids regarding flashing is, that they dont reach full brightness straight away, but not seconds, more like milliseconds, but if your flashing someone, it isnt that important that it isnt at full brightness! the fact that hids were only put on luxury cars is a reason, and the reason is the light output they give, and now they are coming down in price, means that they are being fitted to regular cars, even fords are having them fitted to new cars!! now if they are soooo bad as you say, why the bloody hell are all these manufacturers fitting them??
To other people, if you buy a kit, just make sure that they legal ie are ce or e approved, and then you will have no problems with the law and the mot tester! and when you fit them, you will then realise how good they are and why I am bleating on about them so much!
I have got them on my laguna, but cos I hate my laguna, I am selling it and getting another vw, and I will miss the hids so will be retro fitting a set!
