Listing is for 25 Assorted Colors *SUPER BRIGHT* 12V Instrument Panel and Side Marker LED's. These are replacements for the 194/168 T10 wedge base incandescent bulbs. White LED's generally look good installed behind your gauges for better illumination, while colored LED's generally look good behind the corresponding indicator lenses on your instrument panel and produce a much more vivid color. (Ex: Amber behind seat belt/check engine lenses, red behind oil/generator lenses and green behind turn signal lenses.) Some models use the 194 wedge base and some models use the 1895 BA9S bayonet base. We have both styles in our eCRATER store. Please make sure this is your style bulb before purchasing. Compatible with: 194 168 501 W5W 147 152 158 159 161 184 192 193 259 280 285 447 464 555 558 585 655 656 657 1250 1251 1252 2450 2652 2921 2825 Will light your instrument panel gauges over twice as bright as OEM bulbs.
