alright folks - I'm feeling dumb - used the search facility and nothing! which means I'm the only idiot that cannot work it out. All I worked out that Ita's way of getting water out of the bottom of the light assembly was to hoon around Melbourne!
Have removed the headlight from the bracket mounts, have unscrewed philips head screw on bottom of enclosure.
this removes the light assembly from the body.
Have removed the 'holding clasps or pins' from inside the light.
now...am I trying to remove the front glass panel (and the seal and get access from the front)...or am I going in through the back by removing the bulb receptor/holder?
boy these Philips Extreme globes better be worth it!
Thanks in advance
