I recently changed my car's headlamps from stock 50/60W bulbs to 90/100W bulbs, through a honda electrician, he did all the wiring and installed the relays for the new bulbs. But since then i feel dimming of the headlights , they go dim then bright again and this happens continuously for around 20-30 mins after i turn on the lights after that lights remain normal(bright). The electrician claims that this is a common problem for honda citys and i should not be worried but i am not satisfied by his answer. I even made him change the relays, change the ground connection but the problem is persisting.
If anyone can give an input to my problem that would be very helpful.
I have 2013 1.3 honda city prosmatic.
I did not understand your question but dipper switches does goes bad and does not transfers as much current as needed. I don?t know how he installed the relays but it should have solved the problem as relays directly transfers the current from battery into headlights without bringing the heavy current inside the cabin areas. Dipper switches now handles 1A of current which is much lower the what it used to handle initially so I see no problems with using 100W bulbs without a drop in brightness provided he did it right.
Electricians tend to throw relays in unsafe locations within the engine areas where they do go bad with water or at times they tend to place it inside the cabin areas where it kills the entire purpose of installing it and further endangers the vehicle and passenger for a potential fire.
I think, your electrician did not do his job properly and secondly, small relay boxes are available in scrap yards which should always be used as first it protects the relays and secondly can be easily changed without rewiring if damaged and third, inline fuses protects the vehicle from a potential fire.
I will try to share a picture later which may give you a good idea.
