Bike Model = : ST7
Hello all. Just joined the group after purchasing a 2010 ST7 about a month ago. It’s not pristine, but so far I’m really pleased with it 🙂
One question – it has a LED rear tail lamp unit which blinks constantly (slowly) when the ignition is on, and then rapidly when the brakes are applied. I’ve never seen a rear tail lamp that does this. At first I thought it must be an aftermarket unit, but it looks like it was fitted as standard. I was amazed when the MOT tester passed it, as I was sure it must be illegal here in the UK.
My question is this: can I stop the constant blinking? I don’t mind the flashing when the brakes are applied, but the light is quite bright, and I can imagine the constant on/off would begin to annoy anyone following me, especially in low light conditions. Yes it’s probably good for safety and visibility, but I think a steady light would be better (and would help prevent me being run off the road by irate motorists 🙂 )
Are these units adjustable, or am I stuck with the blinking? Any info would be useful. Thank you!

Is it like ON / OFF at a rapid rate or is it fully on but going from 70% brightness to 100% brightness etc ?
Sorry to ask, if you ever have access to GoogleDrive / DropBox etc , record it on your phone (hopefully we can make out what’s going on) , upload the video to GoogleDrive or OneDrive etc….

My GT carby flickers (it IS on) but because its an older carb model, the stator is the older 11/12 pole type, so lower revs the lights are a little duller until it warms up to about 1800 rpm, they get brighter , the rear light is LED cluster , it does rapid flickers all day long but gets extra bright when brakes applied , the flicker is reduced when revs go up (I am riding) , weird but it’s almost nonexistent with an updated OEM 18 pole stator and flywheel and used a MOSFET Reg Rec to make sure its a consistence 14v all day long (from idle to hot riding), that fixed it mostly.
I say this to say if this could be that ? or your issue is different ? You will let us know further!
Also check your stator and regulator! (ignore that it says 125cc below but follow the images to check stator condition) and your coils (they do make 10,000v sparks, you want to make sure they are doing their job and not overly taxing the charging system)
GV700i (St7) will either have the older 2 Pin coils or the new Forward updated Delphi Coils (looks like shotgun) as Hyosung has indeeded updated the ST7 twice under the hood but keep the bodywork looking the same until they moved on to the new 2025 GV650 that’s out now.Rectifier – How to Test Stator , Battery , Regulator – GT125R Carby
