I give my own headlights a second chance: I installed H18 lamps instead of H7, what came of it?


After albeit an old car, but with Hella 3R xenon lenses, the halogen on the Rapid upset a lot, although it is not the worst halogen, for example, if you compare it with Solaris / Rio and their H4. Immediately after the purchase, I decided that I needed to try to squeeze as much light out of it as possible, or consider installing headlights from a complete set with factory xenon (although later, when I saw how it shines, I abandoned the idea of throwing money away).

First of all, I found out that only 11 volts come to the neighbor’s bulbs. I do not need eternal lamps, I need those that illuminate well. It’s good that VAG makes smart enough cars, everyone is driven by a comfort unit, which, using a PWM signal, generates voltage on the dipped-beam lamps. With the help of diagnostic equipment, I set myself 13.2 V and immediately «saw the light», the beam became wider and brighter

I’ll even say more, I forgot about the idea of ​​doing something further and carried H18 bulbs in the trunk for more than a year. H18 lamps are the same size as H7 lamps, only the protrusion is different in width, and there is also some kind of rounded slot. These lamps are designed by Osram for halogen lensed optics.

Many automakers have switched to 65 watt bulbs for optics with halogen lenses. (Do not rush to shout about STG, wait). The usual H7 has a power of 55 watts. To make the H18 stand up instead of the H7, you just need to take the wire cutters and shorten the long ledge in half, it takes 5 minutes with the installation of the lamps. The photo above clearly shows what needs to be shortened, to make it more accurate, you can use a dremel.

H18 lamps shine like the well-known Night Breakers, even a little better (based on the measurements that I found), but Night Breaker costs from 1400 rubles per set, and I paid 680 rubles for H18, now they break through at 340 rubles per lamp (number lamps 64180L), also these lamps are produced by the well-known Hella, they cost even less — about 280 rubles per lamp.

Immediately about heating, after all, 10 watts of difference. Many will probably write that the lamp will melt everything around and even itself, but in fact it heats up only 15 degrees more than the native H7, this is not critical for my headlight design. But it is important to understand that any “collective farm” is done at your own peril and risk, and, of course, it is important to first weigh the pros and cons, at least look at the headlight device, evaluate what the reflector is made of.

What about the results? I took some photos near the wall. There is a difference, it is clearly visible by the heat spot, as well as by the way the “jackdaw” is filled in on the right headlight, where the H18 already stands and on the left, where the native H7 Philips is still. Also, the light temperature is slightly different, native lamps are more yellow. The cut-off line remains unchanged, this is me for those for whom any replacement of light bulbs inevitably leads to blinding of the oncoming stream.

After installation, I decided not to spare money and went to check the headlight settings. With these lamps, the light remains at the same level as it was before, they do not shine below or above (as is the case with LEDs).

In general, I was satisfied, the light became even a little better, of course, without the “Wow!” effect, but still. I advise all those who want to try «positive» lamps, but do not want to waste a lot of money on them. Thank you all for your attention, don’t forget to support the note with your thumbs up!
