## Before you buy

- Fit is limited to dual-function lamps combining parking or city-light and turn-signal functions. The listing says a 50w 6ohm load resistor or flasher relay may be needed to prevent hyperflash or a bulb that does not blink, and also describes an external decoder requiring additional wiring.
- Listing details are inconsistent or unconfirmed: the title identifies 3157, 3156, 3457 and 4157 compatibility while the feature text lists additional bulb types, and the details state 24 volts while the installation text broadly describes vehicle replacements. Confirm the exact socket and vehicle voltage before purchase. The listing also gives 10 watts overall but describes 5W for each bulb, so the wattage basis is unclear. Its brightness entries use both 2600 lm and 2600 lumens, without clarifying whether the claim is per bulb or for the pair.

## In the box

- 2 LED bulbs (Included)

## A good fit for

- Drivers replacing dual-function 3157-style lamps who want white parking or DRL output and amber turn signals, and can accommodate decoder wiring if needed.

## Less suited to

- Vehicles whose lamp socket does not combine parking or DRL and turn-signal functions, or buyers seeking a confirmed fit for a specific vehicle without checking its bulb and voltage requirements.

## Customer feedback

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller one-star share means the overall score does not establish consistent results. No written customer feedback is supplied, so specific praise or complaints cannot be identified. For buyers, this rating pattern is only broad context and does not resolve the listing's fit, voltage, or wiring questions.

## Frequently asked questions

### What colors does this bulb use for each function?
The listing describes white for daytime running or parking lights and amber for turn signals. It says the signal pattern is amber-off rather than alternating amber and white.
### Will it fit any vehicle with a 3157 bulb?
Not necessarily. The listing limits use to dual-function lamps that combine parking or city-light and turn-signal functions. Verify the vehicle's socket and voltage, especially because voltage and compatibility details in the listing are inconsistent.
### Does installation require extra wiring or a resistor?
The listing says the external decoder requires additional wiring. It also says a 50w 6ohm load resistor or flasher relay may be needed if hyperflash occurs or the bulb does not blink.
### How many bulbs are included?
The explicit included-components entry specifies 2 x LED Bulb.
