Headlights go OUT !!

RQB3263...Well it happened again....coming home in the dark last night my headlights went out ....this has happened before and I thought maybe i corrected it by replacing the headlight "thermal circuit breaker" on the fuse block from a 20 amp up to a 25 amp...About 6 months ago I replaced the OEM incandescent 7" round bulbs with H-4 halogen conversion.....I fear this may be the cause of the outage as there is an increase in heat from the halogen bulbs...fortunately my aux. lights bring me home every time...and after short cool down headlights return to normal operation.....I also have plexiglass headlight covers that certainly impede airflow and bulb cooling....I AM NOW CONSIDERING CONVERTING TO LED HEADLIGHTS WITH A LOWER AMP DRAW AND LESS HEAT OUT PUT......Has anyone done this successfully....where, when and how ?? enlighten me please ....BILL RQB-3263

Thanks for running point on the headlight conversions. I found these on the internet. The supplier is fairly well known for LED bulbs but I have no experience with their headlights.

One thought, take a look at the back of the bulb, there may be some interference issues to deal with in the bucket.

Here's a look at a ton of Ebay listings.

RQB 3263...Thanks for the info ...websites saved...Further tests this morning also show that when the breaker trips off the headlights the tail lights go out also....this is really a bad deal....especially in traffic...im going to up size the breaker at least temporarily and continue investigating LED conversions...ill take all the help i can get ....THANKS...BILL RQB3263

So, did you not follow Bob's (Avanti83) advice that you should use relays and run the H4 bulbs directly off the battery rather than plug them into the old circuits?

Bill,

You don't note what year your car is but, if an early edition (probably pre-1970 -- wiring color-code issue but I'm not sure) you can look in issue #170 on page 47 where there is an article I wrote up describing the headlight relay circuit I used; as noted in the article, it is essentially the same as on Bob Johnstone's website (but slightly different as noted in the article). I mounted the relays up under the fuse block and they are well hidden. I ran the main feed to the lights from the existing 20 amp breaker but, for high intensity lamps, you can certainly feed it from the main battery feed with a breaker or fuse in the line. As with any task under the dash of any car, the job was not hard at all but does require some dexterity. My headlights were dim and occasionally flickered; I've been real happy with the results. Good luck.

RQB3263...NIGHT TEST........PERFECT.....actually better headlights brighter, tail lights brighter, everything electrical seems to function better, ammeter barely off the peg, volt meter up at least 1 volt to around 12.5 or 6 with a/c and high beams and fog lights on 11 volts at a stop light to 12.2 v going down the road...maybe could use a smaller pulley on the alternator...but thats for another day...good night ....RQB3263....BILL
