I have plenty of unused GE #1073 S-8 12.8V 1.8A 23W 32CP BA15S.
Looks real close to me. Am I going to mess up any on-board computer/diagnostics/anything else by substituting a 1073 for a 1057?
I substitute bulbs on my older cars without problems, but I am scared of even deviating slightly on the ML.
I've substitued the bulbs on mine without any problems.
