Cara Mengganti Lampu Motor Secara Aman

Mengganti lampu motor dengan kapasitas watt yang lebih besar tidak dengan sendirinya akan menjadikan sorot lebih terang. Justru sebaliknya, umumnya lampu motor juga harus diganti dengan kapasitas watt lebih kecil untuk bisa mendapatkan nyala lebih terang. Karena terdapat resiko bohlam lampu lebih cepat putus dan mati.

Berikut tips yang perlu diketahui sebelum mengganti bohlam lampu, agar pengguna kendaraan roda dua tidak banyak mengalami kerugian.

Mengganti lampu berukuran lebih kecil

Bila kurang puas dengan nyala lampu motor Anda, sementara tak ingin mengganti dengan halogen atau xenon, maka yang perlu dilakukan adalah mengganti lampu dengan watt sedikit lebih kecil. Kapasitas lampu motor pada umumnya 35 watt. Maka gantilah dengan yang berukuran 25 watt, jangan dengan ukuran 18 watt karena terlalu jauh.

Penggantian lampu lebih kecil 10 watt itu akan dapat membuat nyala lebih terang sekitar tiga per empat kali dari nyala standarnya. Namun umur nyala lampu tersebut juga menjadi lebih pendek sekitar setengah kali dari umur rata-rata nyala lampu standar.

Mengganti lampu dengan halogen

- Pilihlah jenis lampu halogen merek bonafid bila anda ingin menggantinya. Cara untuk mengetahui merek berkelas antara lain dari kesamaan cetakan merek pada pembungkusnya dengan yang tertera di bagian tubuh bawah lampu. Selain merek, pada tubuh lampu tertera pula ukuran dan kapasitas lampu bersangkutan.

- Pada halogen berkualitas buruk, umumnya dalam tubuh lampunya tak tertera merek seperti yang ada pada pembungkusnya. Logam dan filamennyapun nampak lebih kasar dan ringkih. Terdapat beda harga hingga tiga kali lipat antara halogen imitasi dengan yang berkualitas. Penggantian halogen tak perlu mengecilkan ukuran wattnya. Karena halogen yang lebih mahal dapat memancarkan sinar 1,5 kali lebih terang dibanding lampu standar. Jangan menyentuh permukaan kaca lampu halogen kala melakukan penggantian.

- Sebab kegiatan ini dapat membuat lampu halogen menyisakan blackening (kehitaman) di permukaan kaca dalam. Itu terjadi karena begitu kaca tersentuh tangan, maka proses ionisasi dalam bohlam terganggu. Apalagi kalau kaca luar tersentuh tangan setelah lampu menyala, gejala menghitam dipastikan datang tak lama lagi.

Menganti lampu dengan xenon

Keputusan mengganti lampu dengan jenis xenon serupa dengan mengganti dengan halogen. Yang perlu diketahui adalah sifat xenon yang nyalanya lebih terang dan juga menghasilkan panas dua kali lipat dari lampu standar.

Karena itu logam tebal berkualitas harus menjadi bagian yang diperhatikan kala memilih merek xenon. Bagi motor standar penggantian dengan lampu xenon disarankan disertai dengan penggantian dudukan dan kabel yang berhubungan dengan lampu. Sebab dudukan lampu, kabel, bahkan reflektor motor standar bisa leleh karena xenon mengeluarkan panas dua kali lipat dibanding halogen.

Ketahui sistem sumber kelistrikan motor bersangkutan

Ini perlu karena berkait dengan pemilihan ukuran lampu bila memerlukan penggantian. Untuk jenis motor tertentu, seperti di antaranya Honda Tiger, Suzuki Intruder, atau sebagian motor buatan Cina, sistem kelistrikannya amat ditopang oleh aki. Karenanya lampu bisa saja diganti dengan ukuran lebih besar bila menginginkan nyala lebih terang.

Cara paling mudah mengetahui motor menggunakan sistem itu adalah kontak saja kuncinya. Kalau lampu utamanya terus menyala, berarti kendaraan itu menggunakan sistem pengontrol aki. Bila tidak, kendaraan tersebut mengandalkan sistem putaran kumparan untuk menghasilkan listriknya.


Though Robin and Joan Rolfs owned two rare talking dolls manufactured by Thomas Edison’s phonograph company in 1890, they did not dare play the wax cylinder records tucked inside each one.

The Rolfses, longtime collectors of Edison phonographs, knew that if they turned the cranks on the dolls’ backs, the steel phonograph needle might damage or destroy the grooves of the hollow, ring-shaped cylinder. And so for years, the dolls sat side by side inside a display cabinet, bearers of a message from the dawn of sound recording that nobody could hear.

In 1890, Edison’s dolls were a flop; production lasted only six weeks. Children found them difficult to operate and more scary than cuddly. The recordings inside, which featured snippets of nursery rhymes, wore out quickly.

Yet sound historians say the cylinders were the first entertainment records ever made, and the young girls hired to recite the rhymes were the world’s first recording artists.

Year after year, the Rolfses asked experts if there might be a safe way to play the recordings. Then a government laboratory developed a method to play fragile records without touching them.


The technique relies on a microscope to create images of the grooves in exquisite detail. A computer approximates — with great accuracy — the sounds that would have been created by a needle moving through those grooves.

In 2014, the technology was made available for the first time outside the laboratory.

“The fear all along is that we don’t want to damage these records. We don’t want to put a stylus on them,” said Jerry Fabris, the curator of the Thomas Edison Historical Park in West Orange, N.J. “Now we have the technology to play them safely.”

Last month, the Historical Park posted online three never-before-heard Edison doll recordings, including the two from the Rolfses’ collection. “There are probably more out there, and we’re hoping people will now get them digitized,” Mr. Fabris said.

The technology, which is known as Irene (Image, Reconstruct, Erase Noise, Etc.), was developed by the particle physicist Carl Haber and the engineer Earl Cornell at Lawrence Berkeley. Irene extracts sound from cylinder and disk records. It can also reconstruct audio from recordings so badly damaged they were deemed unplayable.

“We are now hearing sounds from history that I did not expect to hear in my lifetime,” Mr. Fabris said.

The Rolfses said they were not sure what to expect in August when they carefully packed their two Edison doll cylinders, still attached to their motors, and drove from their home in Hortonville, Wis., to the National Document Conservation Center in Andover, Mass. The center had recently acquired Irene technology.


Cylinders carry sound in a spiral groove cut by a phonograph recording needle that vibrates up and down, creating a surface made of tiny hills and valleys. In the Irene set-up, a microscope perched above the shaft takes thousands of high-resolution images of small sections of the grooves.

Stitched together, the images provide a topographic map of the cylinder’s surface, charting changes in depth as small as one five-hundredth the thickness of a human hair. Pitch, volume and timbre are all encoded in the hills and valleys and the speed at which the record is played.

At the conservation center, the preservation specialist Mason Vander Lugt attached one of the cylinders to the end of a rotating shaft. Huddled around a computer screen, the Rolfses first saw the wiggly waveform generated by Irene. Then came the digital audio. The words were at first indistinct, but as Mr. Lugt filtered out more of the noise, the rhyme became clearer.

“That was the Eureka moment,” Mr. Rolfs said.

In 1890, a girl in Edison’s laboratory had recited:

There was a little girl,

And she had a little curl


Right in the middle of her forehead.

When she was good,

She was very, very good.

But when she was bad, she was horrid.

Recently, the conservation center turned up another surprise.

In 2010, the Woody Guthrie Foundation received 18 oversize phonograph disks from an anonymous donor. No one knew if any of the dirt-stained recordings featured Guthrie, but Tiffany Colannino, then the foundation’s archivist, had stored them unplayed until she heard about Irene.

Last fall, the center extracted audio from one of the records, labeled “Jam Session 9” and emailed the digital file to Ms. Colannino.

“I was just sitting in my dining room, and the next thing I know, I’m hearing Woody,” she said. In between solo performances of “Ladies Auxiliary,” “Jesus Christ,” and “Dead or Alive,” Guthrie tells jokes, offers some back story, and makes the audience laugh. “It is quintessential Guthrie,” Ms. Colannino said.

The Rolfses’ dolls are back in the display cabinet in Wisconsin. But with audio stored on several computers, they now have a permanent voice.
