The low current draw of LED's fools the control modules into thinking the bulb is blown. Need to get LED's that include a resistor to create the load equivalent of a normal incandescent bulb and hence trick the control module into thinking that the lamp circuit is fine.

Bulbs may have an intermittent filament connection or the bulb contacts may be intermittent; a slight bending of the contacts might help
