OXILAM 7440 Amber LED Turn Signal Bulbs, 4000 lm, 2-Pack

OXILAM 7440 LED turn signal bulbs are an amber-yellow, single-function replacement offered in a two-bulb pack. The listing claims a built-in load resistor, but also warns that some vehicles may still flicker or show error warnings and need external resistors.

At a glance

Listing describes 26 3020 SMD LED chips and a built-in CANBUS driver intended to reduce error codes and hyper-flashing.
Designed for turn signals only. The listing says it is not suitable for DRL or parking-light use.
The stated replacement sizes include 7440, T20, 7440NA, 7441, W21W, WY21W and 992.

Pros and cons

Pros

Amber-yellow output is specified for indicator-light use.
Built-in load resistor may avoid separate resistor installation in compatible vehicle systems.
Two bulbs are claimed in the product title.

Cons

Single-function design rules it out for vehicles needing the same bulb to serve as a DRL or parking light.

What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the detail field gives 24 volts, while the feature text says DC 12-24V. It states 30000 hours in one field and up to 60,000 hours elsewhere, and describes 4000 lm without clarifying whether that figure is per bulb or for the pair. Although it promotes CANBUS error-free operation, it cautions that some listed vehicle makes and multi-pair installations can still flicker or show warnings, potentially requiring external resistors. Confirm the original bulb number and vehicle fit, especially across trims and model years. The listed 21 watts is per bulb in the feature text.

Who is it for?

A good fit for

Drivers replacing amber 7440-family bulbs used only for turn signals, after confirming the original bulb number and vehicle fit.
Buyers seeking a pair of LED bulbs with an integrated load resistor and who can verify compatibility with their vehicle.

Less suited to

Applications requiring a dual-function turn signal and parking or daytime-running light bulb.
Buyers who need guaranteed error-free operation without checking vehicle-specific CANBUS sensitivity or possible external resistor needs.

Frequently asked questions

Which bulb sizes does the listing say these replace?

It lists 7440, T20, 7440NA, 7441, W21W, WY21W and 992. Confirm the original bulb number and your vehicle's fit before buying.

Can these be used for DRL or parking lights?

No. The listing says these are single-function turn signal bulbs and are not suitable for DRL or parking-light applications.

Does the built-in resistor prevent every CANBUS error or hyper-flash?

No such outcome is assured. The listing warns that some vehicle systems, including certain models from several named manufacturers, may still flicker or show warnings and may need external resistors.

What voltage do they support?

The specifications list 24 volts, while the feature text says DC 12-24V. Because those statements differ, confirm the voltage requirement for your vehicle before purchase.
