What to know before buying

Listing details to confirm

Check the original bulb and socket dimensions against the vehicle manual before ordering, since fit varies by vehicle and trim. The listing is inconsistent about package quantity, naming 4 Pack and 4 Count while another detail says 1. It also varies in model and cross-reference lists, gives 39–42 mm fit claims alongside 39, 41 and 42 mm title wording, and assigns some listed uses such as turn signals and side markers without confirming fitment for a specific vehicle. Brightness and lifespan figures are listing claims, not confirmed results.

Who is it for?

A good fit for

Drivers replacing a compatible festoon-style dome, map, courtesy, glove-box, trunk or similar bulb who want white LED light.
Buyers able to verify socket length and bulb type against their vehicle's original bulb or manual.

Less suited to

Anyone who needs confirmed fitment without checking vehicle-specific bulb size and socket.
Buyers requiring guaranteed long service life or freedom from flicker.

Frequently asked questions

How do I confirm whether these bulbs fit my vehicle?

Compare the original bulb number and length with the stated 39–42 mm range, and check the vehicle manual. The listing notes that fit can vary by trim.

What color light do they produce?

The listing specifies 6500 Kelvin and describes the color as Xenon White.

How many bulbs are included?

The title and unit-count detail claim four, but a separate package-quantity field says one. Confirm the selected listing's package before purchase.

Can these be used for turn signals or side markers?

Those uses appear in the listing, but compatibility is vehicle- and socket-specific. Confirm the bulb type and required application before using them in those positions.
