Thanks Misha, Should be a simple matter to get a LED type from ebay, be careful that the LED's will fit through the hole in the reflector. Some people have been caught in the past.

One factor in the choice of LED DRL's is car styling. Hyundai decided to make a styling statement with the i30 by installing a row of LED's similar to the fashion originated by Audi. KIA have decided to install a plain DRL lamp in the Ceed which is functional but not a bold styling statement.

Yer pays yer money and yer teks yer pick............

there are only two models of Cee'd that come with LED DRL and both are more expensive (Prestige and Premium)

before buying some from China, I'd like to be sure that they will fit

Good Chinese sellers show all dimensions of the led's, measure the existing bulb for a guide.

KIA (my car: Luxe) has got P21/5WXL

......is that the car in the  photo?

If so is that a 21watt fog lamp bulb and a 5w DRL bulb?

yes, that is my car in the photo and yes it is fog light and DRL set together in one lamp: on the left - fog bulb 35W   H8L; on the right - DRL bulb 21W    P21/5WXL (in accordance with car manual)

easy to say, but hard to implement (a front mud guard of either front wheel well is to be removed to get an access to a bulb)

Do you want to change them or not 

[Shambles]

If you change from filament to LED, watch out for your dashboard display blinking

I do, but I'll need your help, Phil 

If you change from filament to LED, watch out for your dashboard display blinking 

really?

ordered a pair of this led bulb, so I'll know soon enough whether they fit into my car or not

I've found that bulbs that use 5050 LEDs aren't bright enough.

The newer generation LED bulbs - as in the link below - may be better for DRLs.

unfortunately this site doesn't seem to have English version, thus I can't see if it provides international shipping and figure out a postage fee.
LED represented there appears too big for my car as original DRL's bulb length is 45mm.

Unfortunately, I could only find these types of bulbs sold in China, even though some of the sellers claim the basic electronic parts are sourced from Germany and assembled in China.

this info may be useful I think:

Great post Misha.

Can you post that in a separate thread as well as here?

Looks like superb information which I think I'll sticky
