How are the brightness of your warning lamps? I also just installed a DP tach kit and discovered something that will help make the bulbs brighter. If you noticed, the new fixture that you put the warning lamps into is a large chunk of black delrin (paint doesn't stick very well to it) with nothing more than black hollow tubes for the bulbs to reflect light. That's why they're so dim and one or more listers replaced the bulbs with aftermarket lamps and sockets.
I wanted to retain the original look and make the bulbs brighter. So I went to the hobby shop and bought some white hollow styrene tubing that's 3/8ths inch in diameter (which measures out to 9.5mm; the holes in the fixture are 9.7mm). With the bulbs installed and the face plate removed I inserted the styrene tube and marked it. Then I cut it just short of the mark so it wouldn't rub against the face. Then I just dropped them in. The little white tubes act as reflectors and it does improve the brightness.
Here's a couple of pics of the console installed. The first pic is with lights on; second one with them off. Pay particular attention to the sidestand, oil and neutral lights. The pics were taken in direct sunlight.
Hope this is of use to others and if anybody has any questions fire away.
