high stop light

[Grasshopper]

Hi, My high stop light on Isuzu Bighorn 1996 is not working. Tried to dismount it by removing two clips at either end. One came out with no trouble but the other appears to have been stuck in with glue as I can't get it out. I fear I'm going to have to break it to get it out. Required for WOF. Are replacement high stop lights for Bighorns accessible for a reasonable cost or is it easier to get an aftermarket one. Thanks
