What’s Included

- 4 × 20g silica gel desiccant packs
Seal: Re-use the original foam gasket/seal from your original cap (no new O-ring supplied).
How It Works
Dryalite replaces your top access cap and holds desiccant inside the headlight area to absorb humidity. If condensation returns over time, you can dry and re-use the desiccant.
Re-activating the Desiccant
Microwave: 3–5 minutes at 700W (use a microwave-safe dish; do not microwave any plastic packaging).
Oven: 30–60 minutes at 100–120°C.

How does Dryalite reduce condensation?
Dryalite holds moisture-absorbing silica gel inside vehicle-specific headlight caps. It absorbs water vapour from the air inside the headlight, leaving less moisture available to condense on the lens.
Twist-off cap kits need no cutting or drilling. The sealed-cap F10 kit uses a different fitting method explained in its product details.
Recurring misting, not active leaks. If the headlight is cracked or has pools of water inside, Dryalite will not fix it. Repair the fault first.
Green means recharge.
Remove the silica packets, dry them until the beads turn orange, let them cool, then put them back.
30-day full-refund guarantee
If it does not help, return your kit within 30 days for a full refund.
Questions before ordering.
Will Dryalite fix every condensation problem?
No. Dryalite absorbs humidity from the air inside the headlight. It cannot repair a cracked headlight or deal with pools of water inside it.
Is the silica gel loose inside the headlight?
No. The silica packets sit securely inside the Dryalite cap, away from the bulb and reflector.
How quickly should I see a difference?
Some buyers see an improvement within hours. Allow a few days, as every headlight starts with a different amount of moisture.
How do I choose the right kit?
Choose your model above and compare the product photos with your headlight cap. Contact us if you want help checking.
Can the silica gel be reused?
Yes. Orange means ready and green means saturated. When the beads turn green, remove and dry the silica packets, let them cool fully, then refit them. Never heat the caps or seals.
Do I need to permanently modify my headlights?
Twist-off cap kits require no permanent modification. The sealed-cap F10 kit uses a different fitting method, so check its product details before ordering.
How often will the silica need recharging?
It depends on the weather and your headlight. Check the indicator beads and recharge only when they turn green.
What if Dryalite does not help?
Return the kit within 30 days for a full refund.
