This may seem obvious, but have you grounded the light? In the case of halogen light # QH16CTS the black wire is ground into the hardware and the red is the power wire.

Sometimes AC to DC converters will not put out the correct voltage. Twelve volt systems are actually slightly higher than 12 volts, usually 12.8 volts. If your converter is not putting out the right voltage then that could be a problem too. You can check its output using a multimeter such as # PT89ZR.

Also, and I am sure you have probably already checked this, but make sure the fuse in the converter is good. It is also possible that something happened to the bulb. It takes an H3 bulb.
