Suzuki van van indicator blinking rapidly
 

Hello.
Recently I changed the original indicator in my Suzuki Van Van for a eBay replacement (regular bulbs, not LEDs). I had to cut through the old cable and connect them to the replacement.
They are working fine in the emergency mode, but when I switch them to turn (left and right) they are flashing at much higher rate.
I’m not quite sure what’s the problem.
I will appreciate any advise.
