Title: Safely removing gas changed xenons headlights
Post by: SJKOO01 on 08 May 2011, 19:57:49
I have a facelift with gas changed Xenon headlights and I believe that it's important to remove them correctly so you don't get a heavy shock from them  :-? .

Can anyone advise on how to remove them safely and if there's anything else as well as the obvious disconecting the battery.  Do I need to earth the lamps before removing them from the car or anything.

Thanks.

Disconnect battery. Remove headlights. Fiddle about with the bulbs :y

..........don`t ask Albs to put them back in, he`ll probably start a fire :D ::)

I like to give it about 10-15 minutes from battery disconnection before fiddling, so disconnect the battery, then leave for a bit (or remove headlamps) before playing with them

Cheers for the advice LD  :y.

I take it that these types of lights have some sort of capacitor within the system that needs to discharge all power from it then, with this advice in mind  :-?

You can dive straight in if you like, there won't be anything waiting for you as the lamp is permanently loading the ballast (and therefore draining any caps that may be holding a charge).

Disconnect the battery as advised, and away you go.

The effective "off" time will not be from when you disconnect the battery but from when the lights were last switched off - if you see what I mean.

You will have to remove the battery for access to the N/S one anyway! Unless you hands the size of a 3 year old that is.

Why do use the phrase "gas changed", I'm not quite sure what you mean by that.

Cheers

Yeah, I know you can dive straight in... I just tend to want a cuppa by then ::) ::)

What if you are changing the lamp because it has failed ? will the ballast/capacitor thingy be charged then ? not being funny just asking.

I won't bore you with the technical details (unless you want me to), but HID ballasts won't be doing anything if there is no input voltage.

Taking your scenario at "face value" though, you're gonna get a belt no matter what if there isn't a shunt across any cap that may be waiting if the lamp blows while powered up.
