Because each installation is different, sending units and LEDs are not included with the purchase of an individual gauge and must be purchased separately.

Which sender do I need?

You have the choice of three senders for this gauge. Each sender differs by thread size. We offer 1/8" NPT, M10x1, and M14x1.5. We recommend the 1/8" NPT sender for universal applications where a larger adaptor will be used. The M10x1 sender uses the same threads as the OEM VW sending units. It is typically installed in a blank plug on the oil filter flange or in place of an OEM sending unit. The M14x1.5 sender takes the place of the drain plug in almost every import application.

Which LED do I need?

This gauge includes a white 194 light bulb. For the ultimate in visibility and color we recommend the use of a 194 LED. We offer a variety of LED options for this gauge including basic 194 wedge style LEDs, high intensity LEDs, and perfect match LEDs.

194 Wedge Style LEDs
Basic 194 wedge style LEDs are a great way to light a VDO vision series gauge. We have them available in 6 colors. Priced at $3 per LED, these LEDs provide an affordable and bright color change.

High Intensity 194 Wedge Style LEDs
Our new high intensity LEDs are the ultimate in brightness. When installed in a VDO vision series gauge these LEDs provide illumination which typically exceeds the brightness of most OEM gauge clusters. These LEDs are available in 5 colors and are priced at $8 per LED.

Perfect Match LEDs
Our perfect match LED system provides a perfect match to the OEM VW mk4 instrument cluster. The LED consists of a grouping of 9 LEDs exactly matching the wavelength of the stock cluster built into a custom base and lens. To drive this LED our power regulator is required to regulate voltage and current. When installed in a VDO vision series gauge a OEM color match is achieved. VDO perfect match LEDs are priced at $15 and the required power regulator is priced at $15.

You May Also Need:
This gauge uses VDO's spin-lok mounting system. In some gauge mounts these spin-lok nuts simply will not fit. For these applications we recommend a stud mounting kit. VDO's stud mounting kit includes two threaded studs, two nuts and a U-bracket. In many gauge mounts, such as our VW mk4 triple gauge panels, stud mounting kits are a necessity.
