UW Leak detection..

[off-track]

Ok, in keeping with my alias, I thought I'd toss this out to the DYI crowd..

I've been seeing several threads here lately about difficult to find leaks. I see you can get UV dyes for most any automotive fluid at most FLAPS (even in single/two dose) packs. When I looked at the loan-a-tool programs it appeared that they didn't have the UV light source to complete the diagnosis. Is that true or not? I didn't want to add the suggestion without trying it myself.

Anyhow, (I'm thinking of a low dollar addition to the tool kit) it got me to thinking about maybe changing out the LED's from the now common LED flashlights with UV LED's available at RS for ~$0.90 ea. I see that there are several UV lights you can buy on-line but what's the fun in that? Anyone gone down this road?

There was also this type of thing but it appears that the blue backscatter might be too much?

Would a yellow filter help?
