U need to check the current that runs to your alternator... and then check the voltage supply of your lamp and try put a voltage/current filter(resistor and capacitor) normally 100k and 1000mf electrolytic capacitor so that it the voltage and current going to your lamp can be controlled.

The problem could be with the battery, not the alternators.
