Re: Both signal lites flashing in the front, tail lites are fine

I double checked all my grounds, signal lite buckets,cab/frame/engine/dash cluster grounds are all good and clean. I replaced the bulbs and cleaned the connections..I was thinking about replacing the column anyways (wanted tilt). That didn’t fix it..it is a step side and the rear tail lite assemblies were replaced years ago..if it was the flasher gone bad wouldn’t the tails be flashing on both sides as well?

Does anyone have any ideas where to look next?
The truck is a 1971 GMC shorty stepside
Sounds like your parking and turn light up front are swapped. parking should be dimmer than turn (I think). I had the same problem on my 71 when I bought it.
