The only turn indicators Beaver gave me that can be seen by anyone beside the motorhome are hung on the bottom of the front mirrors. The 194 bulbs in them are about as weak and dim as you can find.
I was in a RV store and found a collection of bulbs for sale. There were three that had the same base as the 194. I bought a couple of biggest ones for 86 cents a peace. They barely fit inside the plastic lens.
I think they are about three times brighter. Maybe drivers beside me will see them now!
