OXILAM 7440 Amber LED Turn Signal Bulbs, 2-Pack

Pack: OXILAM 7440 amber LED bulbs are a two-bulb replacement set for turn signals, with a built-in CANBUS resistor and cooling fan. The listing claims 4,000 lumens and broad fitment across several bulb codes, but compatibility and error-free operation can still vary by vehicle.

At a glance

Built-in CANBUS resistor is intended to address hyperflash and bulb-error warnings without a separate load resistor in most vehicles.
Integrated fan and driver are described as a compact, wireless design for installation in tight spaces.
The maker claims 4,000 lumens and 600% greater brightness than a halogen turn signal bulb.
The product is specified for turn signals only, not daytime running lights or parking lights.

What to know before buying

Listing details to confirm

Fitment is vehicle-specific despite the list of interchangeable bulb codes. Confirm the original bulb type and vehicle fit before ordering. The listing calls the resistor CANBUS error-free but also says errors can remain on some vehicles. It advertises a 2-pack while package quantity metadata says 1, and describes its contents only as “/”. The stated lumen output and brightness comparison are manufacturer claims, not independent measurements.

Who is it for?

A good fit for

Drivers replacing amber 7440-family turn signal bulbs who have confirmed vehicle fitment.
Buyers seeking an integrated fan and CANBUS resistor rather than a separately wired resistor.

Less suited to

Aggregate ratings are mostly five-star, alongside a smaller spread of lower ratings. This suggests generally favorable overall reception but does not establish why customers rated the bulbs as they did or how they perform in a particular vehicle. For buyers, vehicle-specific compatibility and the listing’s caveat about possible CANBUS errors remain important.

Frequently asked questions

Are these bulbs suitable for DRLs or parking lights?

No. The listing specifies turn signal use only and says they are not suitable for DRLs or parking lights.

Will the built-in resistor prevent hyperflash in every vehicle?

The resistor is intended to prevent hyperflash and bulb-error warnings, but the listing acknowledges that some vehicles may still show a CANBUS error and need a load resistor.

Which bulb types does the listing say are compatible?

It names 7440, T20, 7440NA, 7441, W21W, WY21W, and 992. Because fit is also described as vehicle-specific, compare the bulb code and vehicle requirements before buying.

How many bulbs are included?

The title and feature text describe a two-bulb set, while package quantity metadata says 1 and the included-components field is only “/”. Confirm the selected listing’s package details.
