[Lynn Eades]

The Australian Lp2 carrier had a red lense and a blue lensed light,(Blue, front and rear) I cannot recall the logic behind this, but I see in the parts book that the red tail light lense became obsolete.
With regards the brake lights, you are applying modern day thinking to a time gone by. I dont think any of the wwII carriers had brake lights. I would guess brake lights on tanks was the same. Probably on the allied side the Americans would have been first with the standardised QMC tail light assemblies being fitted, as on the M3A1 light Tank (Stuart or known here as the Honey tank)
