Very good discount on same brand fuses you can find in regular auto parts stores selling for double the price. My truck uses these 15 amp fuses for the main cigarette lighter socket, which is probably commonly used in various vehicles. My cheap video monitor connector broke and fuses kept blowing. Together with a new, better plug that I got to replace the defective one, these 25 fuses will last me for a while. The fuse box fits snugly, not too loose and not too tight.
