First you will need to buy some "SONAR" angel eye headlights.

Next Warm the whole unit up with a small fan heater or a hair dryer or blow heater taking care not to overheat the lense.(your doing this to soften the chewing gum type of sealer that holds the lense on.
You can get these quite hot without them melting
Get a screwdriver down the side of the headlight where the headlight lense joins the headlight and prise the lens off the headlight.
You can be rough as hell as the lenses are very very strong and durable.
Now you have the lense throw the rest of the headlights in the bin
You are now left with a lense.

With an angle grinder remove a slither off the sealing edge to make the lense flat .
you should then have a piece removed like this.

then take about 1-2mm away from the outside edge

check that it fits snugly like this

You can choose to paint the chrome bits if you desire but i reccomend you leave it chrome
heres mine in black with a smoked indicator lense

and a set of neon angel eyes fitted also

and to finish off all you do is put a smear of clear silicone sealent on the mating surfaces and pop the clips back on.

and you can add angel eye rings at the same time using the HOW TO on
