As far as what position they occupy in the bulb, I couldn't say. Dual filament bulbs like the # DI79VR have two different filaments. One filament is of a different resistance value, and thus makes a brighter light. but the brake and turn signal filament would be the brighter of the two.
From what you describe, it certainly sounds as if you have the brake/turn signal and running lamp wire reversed. view full answer...
