"Shimano light action FD RD"? lowest line?

I may go look at a bike with shimano derailleurs and I've never heard of the "light action" line. I only hear 105, ultegra, tioga, dura ace etc.

Any insight? Is it the lowest you can get on the food chain for the 80s?

Fairly low, not the lowest and quite servicable if in good condition. Check out Velobase for some more info

These were OEM on mi Miyata 312. Fairly low down the road group food chain, but quite serviceable. The RD has a reputation for failure; but mine lives on installed on my daughter's Shogun 400.

I have them on my Miyata touring rig, and they shift perfectly.

There were several different models of RD, the RD L525 with alloy plates (some models came with steel plates) can be polished up really nicely and looks much more expensive than it really is!

The OEM Light Action works just fine 22 years later on a Lemans RS, 7-sp indexed. And the white accented FD, RD, and shifter tips don't look half bad. I don't know about other years, but the shifters and FD were as good as the 105 of the same era, but the 105 RD was better, in my opinion. There were certainly lower levels offered by Shimano.

Good info, thanks. I won't be too wary of it then if I check out this bike.

During its era, the late 1980s, Light Action was just below 105. It was the least expensive SIS derailleur system, but was also available in a non-idexed version. They were typically found on lower mid-range or upper entry level models, depending on the how the manufacturers wanted to allocate the budget on the remainder of the bicycle. Performance was very good for the price range, however relaibility is a question mark. The strength of the rear parallelogram arm is compromised to incorporate the light action feature. I have seen several break at this point.
