Help Needed with P20A2 MKII Accessories

I recently obtained an EagleTac P20A2 MKII. It's an impressive light. However, there are two things I cannot seem to figure out.

- How do I replace the stock black switch cover with the glow in the dark cover? The tail end of the light comes off for installing batteries. Seems like that piece would further separate to allow for removal of the rubber switch cover.

- By default there is a lanyard ring attached to the back of the flashlight. The manual mentions using a sharp object to take it off. I tried that but did not have any luck. Any advice for how to remove it?

Thanks in advance!

Use needle-nose pliers to take out the switch.
You should be able to take off the lanyard ring without any sharp objects. Post a photo of the problem area.
