Is There More than One Bulb in Optronics ST8RB and ST9RB Trailer Lights

Question

Question:

What type of bulb is the side-marker light in the Optronics ST8RB/ST9RB. I know that the main light in the housing is an 1157 but I cant read what the smaller side light has stamped on it. Thank you.

For the trailer lights # ST8RB and # ST9RB there is only one bulb inside the housing and it is a 1157 like you mentioned. For a replacement you would want the part # A1157B.

The light from the one bulb lights up the side and the front of the assembly.
