1994 VDO speedometer and tachometer. Their performance is a MARKED IMPROVEMENT over the original incandescent bulbs. The speedo has two bulbs, but replacing only one with the LED was sufficient to make the instrument readable from dusk to deep dark. The tachometer, on the other hand, uses only one bulb and the space under the instrument's face is limited. In order to fit into the tach, the LED has to be withdrawn 3/8" from the depth of the original incandescent bulb. Although the light it casts is STILL BETTER than the original, much of the emitted light from the LED is trapped in the tube originally intended for the bulbholder. It is dimmer than the speedo. Only time will tell if the heat from the LED, which is trapped in that bulb holder tube will reduce the LED bulb life in the tach. Horizon's price and service is superb! International shipping (to the US) was fast and reasonable in price. I am very pleased I found these unique bulbs for my automotive instruments.
