    Didn't know if anybody was interested, but I found this pretty neat. I needed a tach cup for an old Sun gauge and I didn't want to spend the money to buy one. I looked around the garage and found some old bicycle lights and liked the shape. It has a hood and little louvers on the underside. It was as simple as gutting the light and slapping the tach in there. You press the little ****on on the side and the front swings open for removal. I'll probably cut a little gasket to fill the gap, but it fits snug as is.

    You say you have some bicycle lights so do you have more? I need one for the same purpose.

    Mine is a re-pop of an old Delta light....$20 at a bike shop NEW,but considered "old stuff".
    Hit up your local bike shop,flea market..... Should be real cheap. Avoid swap meet stuff,unless it's under the $20 mark ,as everything old bike everyone thinks it's gold! I gutted mine,slipped in my OT tach,and good to go. Look at ten speed lights,plenty of pickin's...... Should be easy breazy. I just thought of it one day to hide my tach,and low and behold........

    Seriously, very nice idea. Looks great!

    I have another but it is a little bit smaller diameter. I've picked up a handful at Antique Stores for $5 a piece.

    I just got a good transmitter box for the tach. I'm running HEI on my 250 six. Can I hook the DIST wire straight to my distributors tach hookup? All the instructions I can find are for points.

    Great minds think alike: I had a similar setup for oil and water gauges on my C Cab for a while.
    Sure looks better than a standard "flat" cup.

    Hope my son doesn't see this. He's been wanting a light for his bike, and knows where I keep my stash of old Sun tachs.......
