Hello again Slawson - I bought the same ones, they look far better than the orange ones. On the front edge of the repeater is a little cutout, push a very small screwdriver in to depress the catch then pull the lens out front first. If the bulb is white it needs to be replaced with an orange one.
If you havent done it already you dont need a screwdriver, just place two fingers at the front and push back and towards you at the same time, once the front part is out pull it towards the front of the car and that's it. Dont mean to say every one else is wrong but have seen some nasty accidents with screwdrivers.
