What does this .lua error mean?

As part of a competition I've entered I'm using one of the modpack bodies; more specifically the 60's supercar body (Le Mans racer style). After submitting the car, the recipient got this .lua error when they tried to open my file...
---------------------------
Lua Error:
---------------------------
tolua++ dbcall failed!: [string "--client\functional\CarView.lua..."]:2759: attempt to index local 'headLightInfo' (a nil value)
You can CTRL+C on this to report it.
---------------------------
Aceptar
---------------------------
I didn't use a modded headlight so I'm confused as to what's going on here... Any help'd be really appreciated as I'll be disqualified if I can't get my .lua reliable!
