I have a couple MTH Premier CA-1 cabooses that I have questions about. Will the bulbs that are in the caboose melt when running on DCS?? The lights seem very bright and I am nervous about a fire. The electronics inside show a 7806 voltage regulator along with a couple of caps. Can I add a resistor or two to allow the use of LED'S??? There are a couple of smaller bulbs on the marker lights that need to be changed also.
Any help will be appreciated.

If you leave the light bulbs put a diode in series to the lighting from the pickup roller(s). A 1n4001 diode is sufficient. Using a diode from each roller in opposing directions will protect the roller wire from burning up in a short if there is a derailment. If it has a smoke unit use a 3 amp diode.
Here is a post on LED conversion at least the way I do it,a command and conventional circuit is shown

The series wiring is also good that Bob shows,if it is a simple caboose with 2 bulbs.

Thanks guys! I'm going to try the series way first. A simple way around a problem, and no smoke.

Well I dissassembled the caboose and found all lights plug into the circuit board. Each light except the markers, has it's own plug. I tried cutting one wire from each interior bulb and splicing it in series with no luck.What I may have to do is put both lights on one plug and wire the lights in series. It's my luck, one of the marker lights is DOA. Hello mTH!

Just put a diode in series from each pickup roller wire, then you dont have to mess with the bulbs or circuit board.
