im going to be installing a type r wing on my GS but i will need a third break light

I was wondering can I use one off a civic or something or does it have to be a OEM integra one

 

 

I bought an aftermarket LED brake light and mounted it inside at the top of the hatch glass. I'm assuming that you have a gen 3 Integra. Most likely, your GS doesn't have the bolts in the hatch glass to mount the OEM unit. If it does and you want the OEM unit, I have a dark grey one (Color code D). IM me if interested.
