Clearing Steamed Headlights

[Waitey]

Are there any tips on un fogging the front lights?

In past cars i've always poured a packet of silicone beads into the light unit. I can't do this on the TVR due to the lighing units all being sealed and the lamp cover itself begin steamed up.

Do they stay fogged up all the time?, or just when the worst of the winter sun is on them? If the former then remove, clean, dry, reseal. If the latter than it is normal and TADTS.

Left one is all the time. Right one clears if its warm outside.

Take out the bulb at the back, and heat up the front with a hairdryer/heater. Worked for me

Sounds like you have an ingress of water into the left one giving permanent condensation. One of mine let water in across the horizontal seam. Play some water over the sealing joints using a hosepipe and look for water pooling inside the unit. Automedon cured mine by removing the cover (without breaking)
and then resealing.
