The single biggest reason to buy is the combination of a built-in No Canbus error system and anti-hyper-flash resistor, which aims to avoid error codes and erratic flash rates while delivering substantially higher visibility than stock halogen bulbs. Installation is simple and the bulbs work with most vehicle dimmer switches.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Canbus Error System:\u003c\/strong\u003e Built-in IC chips are designed to prevent error messages on 99% of vehicles, so buyers can expect plug-and-play compatibility in most cars.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Brightness:\u003c\/strong\u003e Rated at 3200LM and claimed to be about 15 times brighter than halogen, these bulbs improve visibility when reversing and make brake or turn signals more obvious to other drivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Heat Management:\u003c\/strong\u003e A turbo silent fan is included in the lamp housing to dissipate heat during operation and help maintain LED performance without extra wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnti-Hyper Flash Resistor:\u003c\/strong\u003e Built-in resistors reduce the chance of hyper flashing on compatible systems so turn signals run at a normal rate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Function Fit:\u003c\/strong\u003e Designed for many 3157-style sockets, the bulbs can be used for reverse, brake, parking and turn signal applications when the socket fits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug and Play Installation:\u003c\/strong\u003e Instructions are included and the bulbs are compatible with the vehicle dimmer switch for simple replacement without modifications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe SEALIGHT 3157 is best for drivers who need a brighter, maintenance-free upgrade for reverse and multi-function lights and who want a bulb with built-in error suppression and heat control.
