Dryalite BMW F10 LCI Moisture Fix Kit | for non Removable cap headlights | Pair
Dryalite absorbs humidity from the air inside your headlight. Choose your vehicle to find the right kit.
Kit: £100.00 - Available.
Fitment and specification
- A relatively simple DIY installation that can help reduce moisture/condensation and save big bills.
- Much cheaper than professional resealing (often ~£250 per side), and replacement headlights can exceed £1,000+.
- Two fitting options: soldering iron method (cleanest) or 60mm hole saw.
- Includes 2 × 50g silica gel packs. If moisture returns, the desiccant can be re-activated and reused.
Developed with consultation from professional engineers and refined with feedback from Absolute BM (Worcester). We carried out test installations on two vehicles before releasing the final version to the public.
For these sealed top-cover headlights, this is currently a unique purpose-built solution intended to help owners avoid the cost and hassle of resealing or replacing expensive units.
- Lid/Cover (screws onto the main body)
- Main body / ring (fastens to the headlight top cover with screws)
- Bottom piece (screws into the ring main body)
- 1 × Drill guide hole piece (only used if you choose the drilling method)
- 8 × M3 self-tapping screws (4 per side)
- 4 × Nitrile O-rings
- 2 × 50g silica gel desiccant packs
- 1 × White permanent marker
- 1 × 2mm drill bit
- Crosshead screwdriver
- Drill
- Either: soldering iron / pyrography tool (recommended) or a 60mm hole saw
- Vacuum/hoover (especially if using hole saw)
- 60mm hole saw: you can find suitable options on Amazon for under £7.
- Soldering iron / pyrography tool: a simple, sturdy tool with a solid, non-wobbly tip works best. Multi-tip sets can still work, but if the tips screw in, firm pressure while hot can sometimes loosen them.
- Temperature: 280–300°C is a guide. You can still do it with a non-temperature-controlled soldering iron/pyrography tool it may just create a bit more smoke/mess, so good ventilation is recommended.
Hole saw method: faster cutting, but cleanup can take longer than 10 minutes. Some swarf can be very difficult to remove without compressed air.
- Position the ring on the headlight top cover in the correct location.
- Use the included white marker to draw a guide circle within the ring opening.
- Heat the tool to around 280–300°C (guide only). Higher is easier to push through but can create more smoke/mess (use ventilation / mask).
- Melt a series of holes around the guide, then join them up to form one opening.
- Test fit: ensure the bottom screw-in piece passes through. The hole doesn’t need to be pretty just large enough without removing too much material.
- Drill pilot holes: keep the ring in the exact final position and drill through the ring’s 4 guide holes using the 2mm drill bit.
- Important: while drilling, hold the ring firmly against the headlight housing so it cannot move.
- Secure the ring with the supplied M3 self-tapping screws (snug, do not over-tighten).
- Screw in the bottom piece (hand tight).
- Place the 50g silica gel pack inside the Dryalite cap, then screw on the lid/cover (hand tight).
- Fit the included drill guide hole piece (used only to drill the pilot hole).
- Using the small drill bit, drill the pilot hole through the guide piece. Hold the ring firmly so it doesn’t shift while drilling.
- Remove the ring + guide piece.
- Fit the 60mm hole saw to the drill (with the pilot drill bit installed) and cut the 60mm hole, using the pilot hole to guide it.
- Vacuum thoroughly. Expect more swarf; some pieces may be hard to remove without compressed air.
- Re-position the ring in its final location and drill the 4 pilot holes through the ring’s built-in guide holes using the 2mm drill bit.
- Secure the ring with the supplied self-tapping screws, screw in the bottom piece (hand tight), add the silica gel inside, then screw on the lid/cover (hand tight).
- Oven method: dry on a low heat (around 100–120°C) until fully dry. Place the packs on a tray and keep an eye on them.
- Microwave method: use short bursts at a low/medium power, checking frequently to avoid overheating.
- Installation involves a permanent modification to the headlight top cover.
- Work carefully and at your own risk. If in doubt, book a professional installation with Absolute BM in Worcester.
- Photos may show a representative setup; you will receive the items listed in “What’s included”.
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.
