Parking light dash warning

Hi all,

Hope this is the right place to post this.

Looking for some assistance please. I replaced my headlights at the weekend (bumper-off job, what a faff) and have now got a dash warning light for the left and right parking lights.

The headlight units are very similar to the OEM units, I bought them from Ultimate Styling - the bulb holders arent as good as OEM but seem to work ok. I've replaced both main bulbs in each unit with H7s (477), and replaced the indicator bulbs like for like.

The 'main' bulbs and indicators work fine, and the inner bulbs (i.e. closest to centre of car, either side) come on when on full beam.

Presumably the ECU is picking up some difference in current/voltage or similar (im no electrician!)?

Any suggestions/advice gratefully received.

Thanks
Dylan

Small as in the indicator bulbs? The others, 2 per unit, are same size (as per the previous set-up) Ill take some photos

Thanks for the quick response

AH what a fool. Didnt even notice them. I even bought W5Ws but didnt think they were needed.

Thanks very much!
