Ya know what Dustin, I gave you some bad advice. Sorry about that it's been a long while since I played with lights.... like 6 years lol
What you need to do is rotate the light model in binedit and add in a additional transparent bin to trick the game engine. Then rotate the model in traxx so it stands straight up again.
Go to the link below and download the 5th model down from the top called 'Working Lights' and study the model and how it is rotated, also check how the transparent portion added in is situated.

If it gives you too much trouble let me know and i'll give it a try but i'll need the light model you want to use.
