Hyundai i30 bulb issue

proracer, Jun 14, 6:16am
Anyone else on here have the bulb blowing Hyundai i30. It a common issue going by the forams on the internet.
Mine is 2009 model.
Headlight bulbs only blow all the time, can't find fault, Tried new battery, Power surger, more earthing.
Yes fitted by professional shop a can't be bothered unbolting car to be able to fit new bulbs

We have a 2010 I30 that's used for rural delivery mail. It's got exactly the same problem ~ we did the same fault test's but found nothing. Yet other vehicles used on the same roads don't have that same issue.

Hey Sorry I have taken so long to reply. My son's i30 diesel is still going great and has not blown any headlights again. All I did to his was I added an extra earth cable from the battery to the Engine direct and a wired anti spiking diodes to the low beams both sides. It seems to have done the trick.

Phillips long life light globes worked for me. There is a post on here somewhere but I went from blowing them regulary to i think it was 60,000k without a globe going. They were still going strong when I sold her.

Does it use an H7 bulb, or any other type with more than one spade connection?

If so then it might be the same issue I had on a Pug, which was that the connector felt like it was sliding and clicking into place firmly and making a decent connection but as it turned out only on one of the two spade connectors. The other was all black and chewed out and only made a dodgy connection causing a sort of spiky flicker which stuffed bulbs in very short order. The fix was to Remove the plastic connector and use two new tight and separate spade connectors. No further issues.

normally bulbs fail because they are cheap crap or from vibration.
typically power supply does nothing to resistive loads like bulbs, in fact filament bulbs help dampen any spike.

the other factor i forgot about, which saxman99 alludes to, is heat.
if the lens is to insulating those bulbs can overheat. also if they have bad connections on the back, those connections heat up adding to the heat load.
i suggest looking at the air flow around the headlight unit and also air flow off the radiator.
easy way is to put a temp sensor there.

i think the extra earth leads, anti spiking diodes etc is a red hearing.(anti spiking diodes work with inductive loads not resistive loads)

No we didn't ~ also forgot to mention that we have the same problem with
the fog/spot light bulbs. I'm not sure if we've tried the Phillips long life globes that scuba posted.

LED is the way to go. they will take a varied voltage. If it was me I would retro fit different bulbs.

Ask a rally driver what they use.

LED not legal I told

Most lights will be led soon. So long as it is the same colour range and lux, who would be able to tell.

if they have been retrofitted. The wof guy when checked on a beam setter

No beam detector at the local garage, line on the wall, All good to go the reflector should do most of the beam angle. Do it on your fence at home. Easy as.

Might just be a Hyundai thing. I drive an iload van for work and amongst other things, it absolutely eats headlamp bulbs, rear door gas struts and the transmission output shaft seal on a very regular basis

How much voltage is the harness to the bulb getting?

Halogen bulbs' output and lifespan are usually rated at 13.2V. If your harness is getting more than that, that may explain why the bulbs blow a lot and why Hyundai halogen headlamps are usually brighter than usual.
