Rated for 12V systems and sold in a convenient pack of 20, they are sized to fit many wedge-style sockets used in automotive and motorcycle dash applications (74 \/ T5 equivalents). They are polarity-sensitive and designed for simple swap-in replacement of incandescent or older LED bulbs when socket type and orientation match.\u003c\/p\u003e\n\n\u003ch3\u003eHow bright and dimmable are these bulbs for dashboard use?\u003c\/h3\u003e\n\u003cp\u003eThe WLJH 74 bulbs deliver about 100 lumens using higher-output 3030 SMD chips, producing strong but controllable red light for instruments and indicators.
