Dual filament 12V bulbs overheating with both filaments on?

I have a phillips 12v 100/130watt bulb for a small 12volt light running both filaments and after 10 minutes the bulb starts giving off faint smoke with a smell. Im not sure if its the bulb itself as it looks like the smoke starts at the base, or if its simply the heatshrink and insulator on spade terminals.

Since these bulbs are for offroad use and high beam usage. Are they fine to run constantly like a few hours both filaments on?
