Standard Rear Bulbs to LED

Post by M140MD » Fri Mar 03, 2017 9:30 am

Just recently done a little swap out on my M140,
It slightly irritated me how the rear indicators were not LED and didn't match the rest of the car.

So ordered a couple of bulbs off amazon and decided to swap the indicator, brake and reverse ones. Looks much better now. Also no errors and I've not had any flickering.

Word of advise to anyone, the rear lights are a right royal pain to get off. So I wedged a microfibre underneath in between light and bumper to avoid any scuffs.

Looking at doing this to my M240i as they much much better.
Does the 1 series have 3 brake bulbs per side similar to the 2 series?
Did you use the same white bulbs from amazon for the brake lights and how do they look?

Yeah they definitely improve the appearance and light output.
Just 1 bulb for brake, 1 indicator and 1 reverse per side. I used the white ones for all as it's a coloured lense what gives it the colour.

Yup. The tail lights are a serious PITA to get out.

That and removing the bulb holders without dropping bulbs in to the lenses.

I've also done a full taillight led conversion on my M135i and its a subtle change but imo makes a noticeable and improved difference!

Not only that, but light output is improved too, especially for the indicators.

My video of before and after below for the indicators:

Edit: you'll also need to code out bulb voltage monitoring to prevent bulb flicker.

Fitted my bulbs but getting the dab cutting out when I brake or put car in reverse. Hopefully when I code the led bulbs check this will improve if not will remove the brake bulbs which is disappointing.

So coded the bulb check out with carly and still dab cutting out so think will remove the led bulbs I purchased. Bit disappointed that they didn't work.

I replaced brake and indicator bulbs and have had no DAB issues (yet). I used only bulbs advertised as CREE (brand of LED) and CANBUS friendly (prevents need for coding)

They were roughly £10 a bulb so a fairly pricey conversion - but IIRC the DAB issues are caused by lower quality circuitry handling the voltage for the LED.

My only question is - do we still get 'bulb out' warnings from the vehicle?

No bulb out warnings even if you didn't code out.

You'd just have flickering leds if you decided not to.

Well that sucks!

I take it we don't even get the rapid flashing of the blinkers to suggest one is out?

I guess I'll need to add a bulb check to my wash routine. =]

Can't say for certain, but with the leds I fitted, even before coding there was no rapid blinkers when using the indicators

£20 a pair from Halfords.

No errors, no DAB loss and no coding for me. Just replaced standard bulbs.

Image

Indicators done, brake lights done and driving lights done. All fine.

Just need another pair for reverse lights and the whole car is LED.
