- Easy tap-in connection
- Gets very hot
- Need one per bulb
Aaron 50W 6ohm Resistors – Turn Signal Only
Brand: Aaron
Reliable for turn signals, but requires careful metal mounting to avoid heat damage.
The Aaron 4-pack is specifically engineered for turn signal use, not constant-on lights like DRLs or fog lights. Each 6ohm resistor consumes 24W in a 12V system, effectively eliminating fast blinking after LED installation.
Heat is a major consideration—these resistors can melt plastic parts if not mounted on a metal surface with screws (not included). The package includes splice taps for wiring, but you’ll need to source your own mounting hardware.
- Effective hyperflash fix
- Includes splice taps
- Clear heat warning
- Not for constant lights
- Screws not included
AUXLIGHT 50W 6ohm Resistors – Aluminum Alloy Build
Brand: AUXLIGHT
A tough, well-built resistor kit that handles heat and vibration well.
AUXLIGHT’s 4-pack features a super-high strength aluminum alloy housing that resists deformation and ensures durability. The resistors operate across a wide temperature range (-65°C to +200°C), making them suitable for harsh environments.
Wiring is straightforward: connect one wire to ground and the other to the turn/brake wire. Each LED bulb requires one resistor, and the package includes 8 T-taps for quick connections. Just remember they get very hot during use.
- High-strength alloy
- Wide temp range
- Includes T-taps
- Gets very hot
- Mounting screw not included
BFXM 50W 6ohm Resistors – 2PC with Quick Clips
The BFXM 2-pack is a compact solution for fixing rapid flashing, false alarms, or bulb failures in LED turn signals and parking lights. Its aluminum alloy shell provides excellent heat dissipation, which is critical for long-term reliability.
Installation involves connecting one wire to ground and the other to the steering or brake line. The included eight quick wire clips make the process easier, but be aware that the resistor generates heat during operation, so mount it away from sensitive components.
- Good heat dissipation
- Includes 8 clips
- Fixes rapid flashing
- Only 2 resistors
- Gets hot during use
AUXLIGHT 50W 6ohm Resistors – Black Edition
Brand: AUXLIGHT
A stylish and functional resistor kit that blends into dark installations.
This AUXLIGHT variant comes in a sleek black finish, matching darker engine bays or under-bumper installations. The 4-pack includes 8 T-taps for easy wiring, and the aluminum alloy construction ensures durability.
It solves hyper flashing, no flash, rapid flicker, and bulb-out indicators on your dash. Connect one wire to ground and the other to the positive turn/brake wire. As with all load resistors, they get very hot, so plan your mounting location carefully.
- Sleek black finish
- Includes T-taps
- Fixes error codes
- Gets very hot
- No mounting screws
ZUDKSUY 8-Pack 50W 6ohm Resistors – Universal Fit
Brand: ZUDKSUY
An economical choice for whole-vehicle LED upgrades, provided you manage heat.
This 8-pack from ZUDKSUY is a generous bundle for those converting multiple lights. It fixes blinker flash errors, no flashing, and burnt-out bulb indications across turn signals, license plate lights, and DRLs.
The resistors control current flow by adding specific resistance, and they’re compatible with any car. However, they get hot, so avoid mounting on plastic, hoses, or painted surfaces. Installation is simple: connect one wire to ground and the other to the turn/brake wire.
- 8-pack value
- Universal compatibility
- Fixes various errors
- Gets hot
- No mounting hardware
UPENGUPENG 3157 Load Resistor Harness – Plug and Play
Brand: UPENGUPENG
A convenient harness for 3157 users who want a solder-free install.

Buyer’s Guide: What to Consider
Choosing the right load resistor involves understanding your vehicle’s electrical system and the specific lights you’re upgrading. Here are key factors to consider before making a purchase.
- Resistance and Wattage: Most LED load resistors are 50W 6ohm, which works for typical 12V systems. Ensure the resistor's wattage matches your bulb's power draw to avoid overheating or insufficient load.
- Heat Management: Load resistors generate significant heat. Always mount them on metal surfaces away from plastic, wires, or painted parts. Some kits include mounting hardware, but many require you to supply screws.
- Wiring Method: You can connect resistors using quick wire clips, T-taps, or pre-wired harnesses. Choose based on your comfort with electrical work. Pre-wired options are easier but may be less flexible.
- Compatibility: Check your bulb socket type (e.g., 3157, 3057) and whether the resistor is designed for turn signals only or also for DRLs and tail lights. Some resistors are not suitable for constant-on bulbs.
- Quantity Needed: You typically need one resistor per bulb. Kits come in 2, 4, or 8 packs. Assess how many bulbs you're converting to avoid buying too few or too many.
Conclusion
Load resistors are essential for a clean LED conversion, preventing hyper flash and error codes. The iBrightstar 4-pack offers great value with its included clips, while the AUXLIGHT aluminum models provide durability. For 3157 sockets, the UPENGUPENG harness is a convenient plug-and-play option.
Always prioritize heat management by mounting resistors on metal surfaces. Assess your bulb count and socket type to pick the right kit. With the right choice, your LED lights will function flawlessly.
