I've got a set of OPTIPLEX, not sure on the spelling, green under-car neons. All four bulbs are for sale. I'm looking to get around $100 for them. It's missing the converter, but that can be ordered from Streetglow.com, for around 15 bucks. It will come with all neccessary mounting hardware and switches. Any questions email me or PM.
