Bulb issue ?

[Megaweb]

When headlight is off. My right rear brake light cannot light up while braking.

 

When headlight is on. My right rear stop light is working but fail to increase intensity while braking.

 

Is the problem due to the bulb or braking system ?

 

My car is KIA RIO 1.4l M HB

 

Thanks :)

very likely the bulb is faulty if the brake light is using the dual filament. Just take out the bulb (the car manual will tell you how to) and look carefully into the bulb, you should see two pair of vertical prongs inside, the shorter pair of prongs will be the normal stop light and the higher pair will be the brake light. Both of these pair should have a winding coil filament connect between their respective pair of prongs. In your case, the winding coil filament could have broken off.

Thanks. I read the manual and it says my bulb is 21/5 watt, so there is dual filament which is 21 watt and 5 watt ? Is all bulb same size ? Any recommending brand ?

 

Thanks again :)

these are the dual filament type, most likely the 21watt (brake light) portion is blown but the 5watt is still working.

 

there are two type, traditional P type and the newer Wedge type shown

Definitely bulb blown. Take out the bulb, go to any stockist with the sample to buy a new one then install it. Dun go workshop, sure kenna . Should costs ard $2-3 for the bulb? Brands like Osram, Philips, etc are fine.
