Question:
1) It is good that I have a source for acquiring proper replacement bulbs. These bulbs have delicate filaments, so I am researching the possibility of using LED substitutes. You might want to stock some for sale. 2) These tail light lenses break way too easily. So far since April 2019, I've replaced every light lense on my Roadmaster Tow Dolly, so are you aware of aftermarket substitute trailer lights that won't break so easily and would fit on my tow dolly?

The bulb type that the Roadmaster replacement light # RM-300220-20 uses as a replacement is the 194 which we have as the part # A194B.
The replacement light # RM-300220-40 uses a 1157 like # A1157B for the stop/tail and then a 1156 like the # DI85VR which is an LED for the turn signal.
