Dryalite Headlight Moisture-Fix Caps (Pair) — F30/F31 3 series 2012-2019

Dryalite® Headlight Condensation & Moisture-Fix Caps (Pair)

Fits BMW 3 Series F30/F31 (incl. LCI) — Upper / Top Headlight Access Cap Type
Replaces BMW 63117311241 (offset/uneven tab twist-lock cap)

Is your headlight fogging up? Condensation can lead to lens staining and expensive electronic damage over time. Dryalite caps use renewable silica gel to actively remove moisture from inside the lamp housing.

Benefits

• Reduces condensation & fogging
• 2-minute DIY install — twist-on, no tools
• Helps protect headlight internals from moisture exposure
• Reusable — regenerate silica packs as needed (instructions included)

Compatibility — READ BEFORE ORDERING

BMW used more than one similar-looking access cap. This listing is specifically for the cap that matches BMW part number 63117311241.

This product fits if your original upper/top access cap matches:
• BMW part number: 63117311241 (often moulded into the inside of the cap)
• Tab pattern: offset / unevenly spaced twist tabs (see photos)

Not compatible: Adaptive LED headlights.
Also not compatible with caps that have evenly spaced tabs (rare variant) — if your tabs are evenly spaced, this will not lock in correctly.

Quick check: Compare your original cap's tab layout to the photos in this listing. If possible, check the inside of your OEM cap for the part number before ordering.

What's Included

• 2 × Dryalite Moisture-Fix Caps (matches BMW 63117311241 / offset-tab pattern)
