1 / 7AUXITO 3157/4157 Switchback LED Turn Signal Bulbs, White/Amber, 2-Pack
Pack: AUXITO 3157/4157 switchback LED bulbs provide white light for parking or daytime running lights and amber for turn signals, with an amber-off flash pattern claimed by the listing. This two-bulb set is intended for dual-function sockets, but some vehicles may need a load resistor or flasher relay to address hyperflash or blinking issues.
At a glance
- White output is listed for parking or daytime running lights, amber is listed for turn signals.
- The claimed turn-signal sequence is amber-off-amber-off rather than alternating amber and white.
- The listing describes plug-and-play, no-polarity installation and compatibility with standard and CK sockets.
Pros and cons
Pros
- Dual-color output assigns white to parking/DRL use and amber to signaling in a single bulb.
- The stated fit list includes multiple 3157-family socket types, including standard and CK sockets.

What to know before buying
Listing details to confirm
This bulb is specified for dual-function lights combining parking/city and turn-signal functions. The listing says some vehicles may need a 50W 6-ohm load resistor or upgraded flasher relay to address hyperflash or non-blinking, although it claims resistors are included, the explicit included-components entry lists only the bulbs, so verify the selected listing's contents. Confirm the vehicle's socket and lighting configuration before purchase. The listing's voltage details differ: one field states 12 volts_of_direct_current while feature text claims a 9V–18V DC input range, treat the operating range as unconfirmed. Its 50 watts and 700% Improved lm brightness entries are not further explained, so their measurement basis is unclear.

Who is it for?
A good fit for
- Drivers replacing a dual-function 3157-family bulb for parking/DRL and turn-signal use, after confirming vehicle fit.
- Buyers seeking a switchback bulb whose listed signal pattern is amber-off rather than amber-white.
Less suited to
- Vehicles with separate bulbs for parking lights and turn signals, based on the stated dual-function-only limitation.
- Buyers who need confirmed vehicle compatibility or assured hyperflash-free operation without checking their vehicle and any resistor or relay requirements.

Frequently asked questions
What color does the bulb use for each function?
The listing specifies white for parking or daytime running lights and amber for turn signals, with an amber-off-amber-off signal pattern.
Will these bulbs fit any vehicle with a 3157 socket?
The listing names several compatible socket types, including standard and CK sockets, but also says the bulbs are for dual-function lights. Confirm your vehicle's socket and lighting arrangement.
Could a resistor or flasher relay be needed?
Yes. The listing says some vehicles may need a 50W 6-ohm load resistor or upgraded flasher relay to address hyperflash or non-blinking. It claims resistors are included, but the explicit included-components field names only the bulbs.
