hi ,welcome to the club i hope you find what you are looking for.
first of all the best place to post this question would be the k11 section, there will be more people there that might know the answer.
and just as a side note, the k11 only came in 1ltr 1.3 and 1.4 so yours is probably the CG10de 1.0 engine,
first thing i would check is the hazzard switch on the dash. if that is not plugged in then none of the lights will work, it may be damaged inside so if you have a spare try that.
if you have checked the flashing relay and ALL the fuses in the engine bay and behind the dash, then that is the only thing it can be. it is very unlikely that all your bulbs are blown, or that the wiring is damaged
