Product Advantages
A premium BAU15S light bulb led replacement, delivering exceptional performance and reliability.
1. High Brightness with 6SMD 2525 Chips
Utilizing 6 high-efficiency 2525 SMD LED chips, this bulb delivers a total luminous flux of 750 lumens, significantly surpassing the brightness of original halogen bulbs (typically 400-600 lumens). This greatly enhances visibility during night driving and in adverse weather conditions. The light is uniform and free of dark spots.
2. Non-Polarity Design for Worry-Free Installation
Featuring an innovative Non-Polarity circuit design, you no longer need to worry about positive and negative connections. Simply insert the bulb into the socket, and it will work immediately. It's truly plug-and-play, saving time and eliminating installation errors.
3. Wide Voltage Range for Broad Compatibility
With support for DC 12-24V wide voltage input, this bulb works stably whether in 12V passenger vehicles or 24V commercial trucks and heavy machinery, offering excellent compatibility.
4. Low Power Consumption, High Efficiency
Operating at only 7.2W, this bulb provides 750LM of brightness while consuming far less power than original halogen bulbs (usually 21W). This effectively reduces the load on your vehicle's electrical system, saves fuel or battery energy, and extends the life of the car battery.
5. Durable and Stable Performance
The LED chips are paired with a built-in constant current IC driver, effectively protecting the LEDs from voltage fluctuations and ensuring long-term, stable operation. The integrated aluminum alloy housing aids in rapid heat dissipation, extending the bulb's lifespan.
6. Multiple Color Options
Available in 6000K White, Amber Yellow, and Red. The 6000K white light closely resembles daylight, reducing eye fatigue. Amber and Red meet regulatory requirements for turn signals, brake lights, and tail lights, making them suitable for various lighting applications.
Application Scenarios
This front turn signal is highly versatile and can be widely used in the following scenarios:
Automotive Lighting: Ideal for replacing original halogen bulbs in reverse lights, turn signals, brake lights, parking lights, DRLs (Daytime Running Lights), fog lights, dome lights, and license plate lights.
Commercial & Heavy-Duty Vehicles: Suitable for tail lights, side marker lights, and clearance lights on trucks, trailers, semi-trailers, and RVs (Recreational Vehicles).
Specialty Vehicles & Heavy Machinery: Applicable for instrument panel lighting or indicator lights on excavators, cranes, and other heavy machinery.
Marine Applications: Suitable for interior cabin lights, navigation lights, and other DC 12-24V low-voltage systems on yachts and boats.
Other Low-Voltage Lighting: Ideal for lighting conversions on campervans, motorcycles, electric scooters, and various low-voltage equipment.
Warranty Policy
Warranty Period: One year from the date of purchase.
Warranty Coverage: Covers quality-related issues under normal use, such as failure to light, severe light degradation, or driver failure.
After-Sales Service: If you encounter any quality issues, please contact our customer service team, and we will provide you with a satisfactory solution.
Frequently Asked Questions (FAQ)
Q1: Is this bulb compatible with my vehicle?
A: If you are seeking a direct 1156 light bulb led replacement, our bulb features a standard BA15S single-contact bayonet base. It fits any socket designed for 1156 (or commonly compatible types like 1141, 1003, 7506, etc.) as long as the space accommodates its size (17mm diameter, 45mm length). We recommend checking your original bulb's model and dimensions before purchasing.
Q2: Do I need to worry about positive/negative polarity during installation?
A: No, you do not. This product features a Non-Polarity design. You can connect the two wires or contacts in either direction, and it will light up instantly. This greatly simplifies installation and eliminates the hassle of incorrect wiring.
Q3: My vehicle runs on 24V (like a truck). Can I use this bulb?
A: Absolutely. This bulb operates on a DC 12-24V wide voltage range, specifically designed for such applications. It can be used directly in both 12V cars and 24V trucks.
Q4: Why are my turn signals flashing rapidly (hyper flash) after installation?
A: This is a very common occurrence when switching to LED bulbs for turn signals.
Cause: The vehicle's flasher relay detects the lower power draw of the LED bulb (7.2W vs. the ~21W of a standard halogen). The system interprets this as a "bulb out" condition and increases the flash rate as a warning.
Is it a defect? No. The LED bulb is functioning perfectly. The rapid flashing is triggered by the vehicle's electronic system.
Q5: How do I fix the "hyper flash" issue?
A: There are two reliable solutions to restore the normal flash rate:
1. Install an Electronic (LED) Flasher Relay
Best Solution: Replace your vehicle's original thermal flasher relay with an aftermarket electronic flasher relay specifically designed for LEDs.
How it works: These relays are load-independent and regulate the flash rate correctly regardless of the bulb's low wattage.
Note: This is the cleanest and safest method.
2. Add Load Resistors
Alternative Solution: Connect a power load resistor in parallel (across the positive and negative wires) to the LED bulb circuit.
How it works: The resistor mimics the power draw of a halogen bulb, tricking the relay into flashing at a normal speed.
⚠️ Crucial Safety Note on Load Resistors
If you choose to use load resistors, please be aware of the following:
Heat Generation: Load resistors function by converting excess electrical energy into heat. They can reach extremely high temperatures (often 100°C / 212°F or more).
Installation Risk:
Do not mount resistors directly against plastic bumpers, wire harnesses, or other heat-sensitive materials.
Always mount the resistor on a metal surface (metal chassis) to act as a heat sink.
Ensure the resistor is not in contact with any flammable materials.
Failure to manage heat properly can lead to melting plastic or fire hazards.
Recommendation: For most modern vehicles, replacing the flasher relay (Method 1) is the preferred and safer option.
Q6: Is this bulb compatible with CAN Bus systems?
A: yes, some modern cars with sensitive CAN Bus systems may still trigger a "bulb out" warning on the dashboard due to the lower power consumption. If your vehicle displays warnings, you may need to use it in conjunction with a specific CAN Bus decoder or load resistor (as described above).
Q7: How bright is this bulb compared to my original halogen bulb?
A: An original 1156 halogen bulb typically produces 400-600 lumens. Our bulb delivers up to 750 lumens, a brightness increase of approximately 30%-50%, while consuming about 60%-70% less power. It's brighter and more energy-efficient.
Q8: What is the warranty period?
A: We offer a one-year quality warranty from the date of purchase. If you encounter any product quality issues during use, please feel free to contact us.
