Chinook RV

I have some hail damage to the forward marker lights and I am having trouble finding an exact replacement. Does any one have any suggestions?
We have a 2001 Concourse. Thank you in advance for any advice.

I got mine from a trailer store. I see that the part list on the Reference subforum says "MC48RBP and MC48ABP Manufactured by Optronics" are they the right ones?
