Please make sure this is the same style base your car uses before purchasing. Look at our pictures for measurements. Listing is for 10 check engine, seat belt and stop/hot/temp engine dash indicators. Kit includes 5 Red and 5 Amber/Orange bright LED's. Also used to illuminate dash gauge idiot/indicator lights. Please do not confuse these with the 168/194 wedge base. These are replacements for the 17, 18, 27, 37, 58, 70, 73, 74, 79, 85, 86, 206, 207, 286, 306, 307, 308, 406, 407 & 2721 T5 wedge base incandescent bulbs. Example: For more vivid colors use red LED's behind red dash indicators and amber LED's behind orange check engine indicators. These LED lights are dimmable just like regular light bulbs in your dash. LED's are polarized and must be installed correctly or they will not light. If LED does not light, simply turn it around the other way. We Ship WORLDWIDE!!!
