I've wired the rear tail lights (upper) indicators etc., and now the
hazard fuse blows when I switch them on. QUESTION is how do I fix this problem - can I install a relay and where, or can I get lower wattage globes for the indicators and where?
Thanks In Advance

This is how you calculate it:
Volt x amp=Watts
Watts / volt =amps
Original load one side= 2x 21 watt globes plus 10watt side plus 5 watt dash.
(Add one more 21Watt if you have a bullbar with lights ie: genuine)
21 + 21+ 10+5= 57 watt divided 12 volts= 4.75 amps (one side only) all four (hazzards) is double 9.5 amps. Original fuse is 10 amps
Add another two 21w globes = 3.5 amps. 9.5 amps + 3.5= 13 amps "there is your answer"
a 15 amp fuse needs to be used because you increased the load.
The same thing applies to all electrical devices.
The same thing applies if you enabled the upper tail/stop lights.

One more thing.
You will not overload the wiring, the wiring can stand more than that, the next thing that will get overloaded ie: if you hook up a caravan with another bunch of lights, is the flasher unit.
The flasher unit is a self regulated one so it does not increase or decrease speed but it will get hot and cut out (if overloaded)
If a short or an overload was significant enough to burn the wiring the 15amp fuse will blow first.
