Hi, I use those MTEC blue coloured DRL bulbs and they are bloody useless. They look great but blow all the time, the same two month lifespan on average. I've thought about the LED's too but are worried about them lighting the dash bulb out warning light. Keep us informed of your LED's.
Those led ones you put the eBay item number for are the ones I bought and from the same seller too! Very bright but you need to mod the pins as shown in the other drl thread that's on here, or it will.blow the fuses for the sidelights and the drl's.
Are you sure that the eBay item 261480583941 (Privatedoc, above) is suitable? They are described as 7.5w LED....but the DRLs are twin-filament (5/21w). There are dual-power (5/21w) LEDs available that simply replace the original bulbs with NO modification of any kind.
Example; eBay item 271003154785...with excellent reviews from Citigo and up! owners.
