Can the bezel, pointer and led light be changed ? I was looking at the 4487M with a chrome bezel, anodized pointer and blue LED but would really prefer if the background dial was black rather than white

Thank you for your question. Yes, after we have received payment for the tach, you can either send it to us or request a certain mileage upon purchasing the tach and we can set the odometer for you. Only we can do this at the factory and miles cannot be taken off an odometer for legal reasons.

I have one of these fitted in my 1975 Mazda Rx4 (929) I have fitted it as per the manual instructions but I am finding that the Speedo is dropping you off every now and then sometimes for 5 to 10 seconds sometimes for a minute what would this be due to?

Hi there, thank you for connecting with us. This will likely require some additional dialogue and troubleshooting with our Technical Support Team. I would recommend sending us an email with a detailed explanation of the problem you're experiencing and the type of sender you're using. Here is the link to email us.

Hi Luke, thank you so much for contacting us. The bulb can be accessed directly from the back of the gauge. Depending on when it was manufactured, there will either be a black cover on the top middle of the back side or a directly wired socket in the same location. It should be extremely obvious as soon as you see the back of the gauge. The bulb is a 194 style wedge base. We offer some LEDs which you can see here:
